I don't mind x or RET in terms of mnemonics, but my clumsy fingers find
them less ergonomic than C-x K K.

FWIW, I don't find it shocking that other-{frame,tab,window}-prefix do
not end with identical letters.  True, they are the only commands in the
{ctl-x-4,ctl-x-5,tab-prefix}-map keymaps that break this convention, but
they still follow a consistent pattern: C-x K K, where K is the prefix
key for the relevant UI element.

I also support Juri's suggestion to bind tear-off-window to C-x 4 5: I
feel like the "_4_ to _5_" sequence translates quite well to "move this
_window_ to another _frame_", at least in my head.
