Well...improvements 1-3 and 5-6 sound very well to me.
Number 4 - removal of the Touch Bar - would in my opinion be a huge downgrade from a currently very well-working Keyboard improvement, but that is just if reverting to conventional F-Keys (like in the current MBA and external Magic Keyboards).
But that would not be the way Apple usually handles things, so my guess is that moving back to "dumb keys" is completely off the table anyway.
If instead a smart successor of the already well-working Touch Bar is in the making - something like adaptive keys or so - then of course I'm quite curious what to expect here.
Nevertheless, glad that my M1 MBP turns out to be the most perfected iteration of the "old" MBP design, with a very-well working and durable keyboard with Touch Bar. So I can lean back and see how the new design looks like, and maybe in a few years when the childhoods diseases of the new generation are resolved (...which took more than 3 years for the keyboard of the current generation, remember!) switch to the new generation.
