Honestly, I'll get over it; I'll set up other key chords to take the place of the various F keys I use today. It still bothers me that I'm the one who has to make these adjustments to support something that I have no need for. It's a short term productivity hit, combined with a long tail of annoyance as my hands use their muscle memory and will incur some random state change on my computer.
macOS has a built-in option to remap caps-lock to escape. I haven't used it yet (I'm not a VIM user, so I mostly just use it to cancel dialogs), but I've ordered the new MBP and it's the first thing I'll do. Should take care of that issue and even improve ergonomics.
I should have remapped caps-lock ages ago, I never use it, but haven't had the incentive until now.
I do, however, always look at my keyboard when I adjust the screen brightness or volume, or control iTunes (pause, next, previous).
The one exception to this is ESC, and I use it gratuitously.
