No, it's a controversial change.  Just imagine typing M-SPC at the end
of the paragraph.  It will join the current paragraph with the next
paragraph.  IOW, it will work as two commands `just-one-space' and
`delete-blank-lines' combined.  I don't think users will appreciate
such change.

Also we can't guarantee that some code won't break with your change.
For instance, try doing the same in the command `delete-horizontal-space'
(i.e. adding \n to `skip-chars-...') and see how it breaks
paragraph-filling commands.  The same bad effect is possible
for `just-one-space'.

However, your proposed change could be useful when its additional
functionality is requested intentionally, e.g. with a prefix key:
`C-u M-SPC'.
