As for MX lock: it's semi-rare. I have one or five myself, so it's not that bad!

Back when keyboards could only send data to the computer, when they were unidirectional, latching keys were fine for maintaining state like CAPS LOCK. A latched key was a nice physical indicator, and folks were used to them from manual typewriters. But once the host machine could talk back to the keyboard, latching keys became problematic because they could so easily fall out of sync. The host can see the state toggle but it can't reset it!

You see this in Hasu's TMK. He supports latching caps lock, but has to handle it quite differently from the normal momentary key.

Before they became super-rare, I put a Cherry MX Lock switch on my ErgoDox for toggling the embedded numpad layer.
That use-case doesn't require any synchronisation with the host, because the layers are all on the keyboard.

BTW, hasn't there been a latching key switch that could be unlatched with a relay?
I'm pretty sure that I have at least seen a post around here of a computer keyboard where the Shift keys were mechanically linked to break the Caps Lock key, as they are on a mechanical typewriter.
