For programming, I wonder if there isn't a lot of low hanging fruit just by key remapping. For instance, a large proportion of keystrokes must be for opening and closing brackets, which requires two fingers for shift + the key.

I bet I press brackets more than "d", "f", "j", "k" - the best positioned keys in QUERTY

I have a keyboard[0] that supports a concept of layers which means if I press a key (or hold it down) the layout changes.

With this, I have it set such that the keys i o, and k l, are for curly braces and parentheses. My left hand holds down the trigger to swap layers and so that my right hand doesn't have to move much if at all to hit these keys.

Yes! I dove into this (and later, Moondlander) because I have mobility issues and had to reduce travel, but the resulting 90WPM and (unprovably) faster coding have been awesome side-effects.
