Exception list for require-prior-idle-ms

[alex35mil]

I configured home row mods using urob's approach, and it works great except for one case I keep bumping into. For example, when I hit ⌫ ⌫ ⌫ and then some character with mod, eg, ⌘ S or any shifted character, it often results in two characters printed instead of mod + character because of require-prior-idle-ms. Is it feasible to introduce a configuration param to exclude particular keys (like, ⌫ or even all non-alphabetic chars) from this rule?
