Hmm. I've pulled this, but "fix" it isn't.

There's no actual bug in the old code that I can see. It' just that
local kmaps are the preferred model these days.

Yeah, that's true. I figured it was better to get it in ASAP to help with
the transition and avoid having both APIs in the same file. Thanks for
taking it!
