Have to confess I have not read every single post, but I don't understand the issue(s).
--Use of the compressor on a hot day is obvious.
--Use of the compressor on a very cold day is not possible, it stays off if the ambient is below a certain threshold.
--Use of the compressor on a cool day will result in low-humidity air from the vents.
--Use of the compressor will result in slightly-worse fuel economy.
So if I choose to NOT use the compressor on cool days, I either want to save fuel and/or I like humid air. These days, the compressor consumes very little power, so all that's left is whether I like humid air or not. Since humid air tends to fog the windows, I figure car engineers assumed nobody wants fogged windows, hence the default use of the compressor.

Yes, i think some of the confusion here is thinking a/c is only for making very cold air from the vents. It isn’t.
Also, we seem to be discussing 3 main scenarios:
1. Full auto
2. Full manual
3. Partial auto/manual
1. And 2. Are pretty straightforward, although there might not be enough separate controls these days for full manual as has been pointed out.
For 3., there’s simply too many scenarios to please everyone. Most people do 1 or 2 or when they do 3 they usually crank the temp way high or way low and adjust fan speed and vent selection.
Trying to manually control some elements while expecting a car to do other things in a specific automatic way isn’t reasonable.

Some people like to use the A/C in a manual mode. For example, if the outside temp is 50F, I could easy drive part of my trip with just the vent and air flow open, while every once in a while cycle in the A/C. Just becomes much more difficult and annoying if there is no dedicated A/C button. Luxury should be ease of use.

They have focus groups already

Using A/C for making cold air is not the issue, ^^^ just came up in the discussion.

If being able to control every facet of the HVAC system at all times is that big a concern to you, then you should prioritize finding vehicle that allows you to do that...and a Lexus vehicle is not for you. Its really just that simple.

Tell what story? I believe Toyota/Lexus knows how to design a vehicle that fits their customers needs and wants, if they didn't they wouldn't be as successful as they are. They use focus groups and feedback about their vehicles to refine them as all designers do.
At some point you have to just chock it up that you have a different set of preferences than the consumer they are designing these vehicles for...that doesn't make you wrong and it doesnt make them wrong. There are lots of vehicles out there who's design interface and feel just aren't to my taste. Doesnt mean that there aren't lots of other people out there that buy them and find them desirable. I don't spend time complaining about the choices those carmakers have made, I just buy what works for me.

Topical:
Kinda goes into why decision like nixing the AC button happen. You have to sell to the buying public - or at least, appeal to the majority of consumers who buy a vehicle.

In some cases, you're putting the cart before the horse. If auto-systems always did that great a job, people wouldn't have to fiddle with them manually. My experience with climate-control, in almost every vehicle I've owned, is, if I want it done to my satisfaction, do it myself.
What you want is control over the functions of the system, and that's fine but you have to understand most people just want to set the system and forget it. If you would let the system do its job, you too would be comfortable. If that wasn't the case, cars wouldn't have automatic climate systems, they would have manual controls.
Carmakers respond to customer demands. Great example of this is touchscreens. Carmakers went away from touchscreens, and buyers complained and you're seeing the industry respond to that by bringing them back.
