That point about toolchain complexity just reminds me of where compilers were 20 years ago. You could get significant speed bumps because one vendor had an optimisation another didn't. That's probably still true for things like the intel compiler, for all I know. I do remember at one point doing computer vision stuff before NVidia ate the world that it wasn't uncommon to come across code that expected to have access to intel-compiled maths libraries to be able to run in real-time.
The point is that the free toolchains got good enough that in general you don't need to care, and I think it's reasonable to expect the same dynamics to apply here.
