I never meant to imply they didn’t, but I never really used them because they weren’t very discoverable. With the Touch Bar I can tell just by looking at the “keys” what they do, whereas with fn-keys all I see is F1, F2, Fn... none of those tell me anything.
I can find out, sure, but my experience tells me I won’t, so for me the Touch bar is a win, simply from a discoverability standpoint.
My 2016 MBP has icon labels for each function you listed right on the F-key, except step debugging. Totally discoverable, just by looking, the exact same as the Touchbar. Those same icons have been in the same spot for the three other MBP's I've owned dating back to 2008.
