Or, a flag like --maintainer-mode that enables all commands _and_
implies -Q and "-l $EMACS_MAINTAINER_RC" if found?

Frankly, I see no reason this issue is controversial: the command has
caused data loss for multiple people; accidental data loss and data
corruption is the worst thing that can happen to you in personal
computing, and accidentally hitting M-~ causes accidental data
loss/corruption in a very confusing way. "(emacs) Disabling" states:

In this light, it’s rather obvious what to do: protect users by
disabling this command.  The sole argument for keeping it enabled is
essentially the convenience of a single person.

Also, something like this

      emacs -Q -e "(enable-command 'not-modified)"

works for Eli’s case, you could just alias it to something like ‘emacsq’
or ‘emacs-Q’.
