Both of our cars (BMW's) have auto hold. When we first got it I was meh but now it's become a must have on future cars. Especially for city and suburban driving.

Same, I love brake hold. I hate that the Pacifica doesnt have it since I'm so used to it

It's not a feature I've ever warmed up to, but I know many really enjoy it.

If the vehicle has auto stop/start, it has no way of maintaining enough pressure at a long stop to hold brakes. That's why so many cars don't have it. I haven't ever seen one with both unless it was a hybrid and had a separate battery powered pump that held pressure until the engine restarted.

Most vehicles today have this feature.

As mentioned previously both of our cars have auto hold, and they both have auto stop/start too. They both work very well together and as mentioned are becoming fairly common these days.

Ok, so we've established many cars have it with auto start/stop. Interesting. I haven't ever seen it on anything other than my LS.
The LS uses the service brakes. I know because the electric parking brake in my LS you can hear with the windows down. It whines and then clicks. no whine and no click when using brake hold with the windows down. Also, when the brake actuator fails, brake hold will not function. But the parking brake does. That could just be software programming though.
No, most vehicles today do not have that feature. Maybe most of the cars you drive today have that feature. I drive thousands of cars a year, of all makes and models, and the only one I have seen with it was my LS460. That's not to say that most higher end cars don't have it, because I am sure they do, but to my mind it hasn't become mainstream in your average car until just the last 2-3 years. Most cars on the road today are older than that. You think a 3 year old Chevy Cruze has brake hold? Dream on LOL.
Auto hold typically doesn't use the service brakes, so zero hydraulic pressure is required. It sets the electronic parking brake, which by design will continue to remain set permanently for months on end if needed, without the engine running or even if the battery is removed. Then when you touch the gas, it releases it.

Electric pump, or it uses the parking brake.

I don’t think it uses the parking brake until a set period of time. I looked up Cadillac and it states the parking brake engages after 5 minutes but the car maintains brake pressure during that time. Toyota doesn’t have many start stop models so it’s hard to filter through. Parking brake comes on if the seat belt is unfastened. There has to be some info somehere
