There probably are some disabled commands that each of us use all the
time.  ‘erase-buffer’, ‘upcase-region’ and ‘downcase-region’ are some
for me.  I think ‘not-modified’ is at least as risky as those commands
given it can be hit accidentally, maybe more easily, as I've said
previously, for someone using a keyboard where tilde is easily
(mis-)typed (in my British layout keyboard it's just to the left of the
big return button: jkl;' then #/~), and indeed would be «confusing for
beginners», quoting the disabled command buffer.  Also, from Glenn
Morris' message in this thread, there seems to be two other times in
history where a similar request to mine has been made.  If my patch is
refused I'll just have it disabled in my config, but I truly think that
this command, bound to a non-prefixed binding in the global map, is
potentially confusing and dangerous for who doesn't already know it,
beginner or not; if we have upcase/downcase-region disabled, this should
be disabled too.
