The manuals I've driven never had this. I've driven cars with both foot and hand brakes and for manuals neither was very friendly if you didn't know how to use the clutch properly. One of those cars also had the high beam as a button you used your foot to press under the parking brake pedal. It took a lot of practice with one of those cars. It had a very finicky clutch that was either on or off with very little play in between. I had another manual where the only time I ever used the clutch was to go in and out of first gear or reverse from a stop. I could upshift and downshift just by rev matching. I also learned to do some interesting things using my foot to hit both the brake and the accelerator to get the engine to rev up if I were on a hill because the car was so gutless. My current car is the first car I've owned with a hill hold feature. It was added in a software update. I never really saw the need for it. My Tesla behaves like a cross between a manual and an automatic with the way I have it configured. I let up off the accelerator and it decelerates strongly. If I'm stopped and I lift my foot off the brake (and I'm not on a hill), the car rolls like a manual with the clutch pedal engaged with no creep like an automatic. Basically as far as I'm concerned hill hold is needed for inexperienced drivers or those with slow reaction times or if you have a really gutless engine.
