I intentionally took a performance hit by moving from a Pro to an Air almost entirely for this reason (although the low power and light weight are pleasant benefits). I'm glad that the new Air still has F-keys with Touch ID; but I'm flabbergasted that they're still not making the Touchbar optional for the Pro series, given how polarizing it's been, and the underwhelming adoption of new Touchbar functionality by third-party developers.
I mean if you think about other professions that use Macbook Pro they don't need it either. Are video professionals using it to scrub through video? Nope. For any audio professional it's useless. No one who is serious about their profession would use it.
I'd be curious to know what portion of their user base for the Pro series are developers. Anecdotally, quite a lot of devs seems to use Macs; but I have no idea what that fraction is, relative to the rest of their market.
