> proponents of mechanical keyboards say you need fewer keys than a regular keyboard, for _reasons_
Well "reasons" is quite obviously travel distance and thus time. If your fingers are always on, or nearby, the resting position (home row) then you go faster and don't stretch in repeated weird (ergonomically speaking) ways.
This though comes at a BIG cost, namely layers and other tricks to make "far" thing stay "close", which is cognitive. You have to remember where things are and how to activate them. Until it comes second nature because you drilled for so long then it might not be worth it for most.

The "reasons" are not arbitrary.
