M-\ and M-SPC are fine, of course, but I think it would be fine to have
other commands that combine both behaviors: delete whitespaces if there
are, otherwise delete the character forward/backward, a DWIM style.

Actually nothing, I'm proposing 2 DWIM-type commands (or a minor mode)
for this hungry-like deletion, similar to c-hungry commands.

`backward-delete-char-untabify` has 2 interesting hungry-like deletions,
one that only deletes both tabs and spaces, and other that deletes _all_
whitespaces.
