+1.

[But isn't this essentially bug #26712? and 2270?
(which was closed as Done, but with no key binding)]

IMO, we should bind `find-library-other-window' to
`C-x 4 l' and `find-library-other-frame' to `C-x 5 l'.

[And this is from someone who doesn't Emacs to waste
key bindings.  These bindings just make sense.  I
almost never use `find-library'.  I use `C-x 4 l'
(which, because I use non-nil `pop-up-frames', opens
in another frame).]

Maybe this will happen in another decade or two?...
I proposed this in 2007 (as soon as `find-library'
was added, if I'm not mistaken).
