For humanity, taken as a whole, I think.  :-)

I agree with the general sentiment, but consider the amount of bugs
that Michael linked where the name "emacs" crops up.  Appearances
matters, to a certain extent.  To my mind it would be preferable, in
general, if we could avoid having a bunch of bug reports (because of
someone elses sloppiness in this case, yes) where it initially and
incorrectly may look like the culprit is "Emacs and its backwards
practices".

More importantly, I think, is what I mentioned before: this could
inconvenience users trying to run stuff using "find -iname '*.c'" and
the like, only to run into emacs lock files.  I do expect the tools
above to get their house in order and just Fix Their Bugs, but random
users doing one-offs is a different question.

That said, I don't feel super strongly about this.  I consider it a
minor cosmetic blemish.
