In this instance perhaps Apple thinks that everyone having one will encourage developers to use it.
But for me, I completely ignore it and force it to behave like function keys, although it does this very badly because I have to look down to see where the "keys" are when debugging (eg F6, F7 in xcode) because I can't feel them, and also it is completely invisible in daylight, as others have stated.
I routinely use my old 2012 MacBook instead to actually get work done because the touchpad is so useless as a keyboard (and turns itself off after a while, unlike REAL keys that don't disappear if you don't give them attention for a minute or two).
A real crying shame.
