Changing Emacs' behavior upon loading a file is very bad.  We already
know this (we even put it at the top of our coding conventions), and the
fix is trivial.  So from my point of view, there is no need to wait for
users to tell us about it; we can act on it immediately.

In comparison, I consider changing `auto-mode-alist' upon enabling a
major mode a mere annoyance.  I'll be able to hack my way around it
myself, of course, but I think it will make for a bad user experience.
Especially since it breaks our existing conventions: users are not
trained to know that enabling a mode in one buffer will change
`auto-mode-alist' globally.  It is surprising, to say the least.

Restarting Emacs is not a solution at all.  It breaks my workflow, and I
know that it breaks that of many users (e.g. those that start Emacs as a
daemon when logging in).
