It's an optional argument, so I fail to see how is that "pollution".

So?  A malevolent enough programmer could replace
keymap-global/local-set with an implementation that performs the
conversion unconditionally, so the danger of someone hanging
themselves with the rope Emacs gives them always exists.  This
function is supposed to help those who _want_ such problems to be
caught, it isn't supposed to make Emacs a high-security prison,
because that's simply impossible in Emacs.

Excuse me, but that's the tail wagging the dog.  Please be reasonable,
we want a change that is simple and safe enough to go into Emacs 29,
because currently those functions are completely useless as
interactive commands, and we want them to become the mainstay of
binding keys interactively.

Over Lars's disagreement?  I don't want to do that, with all due
respect to Stefan, certainly not on emacs-29.
