There is no point in using both latex-mode and LaTeX-mode to mean
something differently.  There is a (albeit minor) point to using both
plain-tex-mode from tex-mode.el and LaTeX-mode from AUCTeX, though.

That would mean that pretty much all mode-sensitive functions from
AUCTeX would break if you tried using them in a latex-mode started
session and vice versa.  I don't see the point in providing different
function bindings to latex-mode and LaTeX-mode.

I am relying on that part of the behavior that is not broken.  If I
insisted on using and programming for only systems that are completely
unbroken in all respects, I'd not be using a computer.
