Is there any way we could reasonably deprecate using uppercase letters in module names?  (If only we could declare aliases of modules, we could make the old name a deprecated alias for the new one....)

Not according to this: http://en.wikipedia.org/wiki/Filename

Moreover, it seems that anything which doesn't retain case, doesn't allow very long filenames. I can't see any reason to require lowercase. It is simple to require that filename case matches module case.
