Earlier quoted context omitted.
The main issue of this is just like with touchbar and similar solutions - power users don't look at the keyboard, so the usefulness will be minimal.
I think HN is a bit unfairly biased against the touchbar, since it serves almost zero purpose for programming work. However, it's quite handy when doing multimedia work with applications that integrate with the touchbar (Logic Pro, Final Cut Pro, Photoshop)
I personally never used the F keys for anything so don't really care if they are there or not (I use them just for brightness and mute) but the Touch Bar was too sensitive. And while I initially thought it would be cool to have an extra status display, a display someplace nobody ever looks is pretty useless.
