Sure, people won't deliberately use bizarre choices of mixed case except
to deliberately prove a point, but it seems undeniable that allowing
case insensitivity _will_ result in different people using different
capitalization conventions.  To use your example, some will write
`maximumcolumns', some will write `maximumColumns', and some will write
`MaximumColumns'.  This is, needless to say, obnoxious.  I don't think
you can really argue against this point, since the case insensitive
languages I've been exposed to one sees it over and over again.

But the convention is much weaker if anyone can write them as
`constants', thus diluting their usefulness as a convention.  It's not
as strong a point, but it still opens itself up to variation -- and that
variation is inevitable, unless you institute draconian style guide
which amount to enforcing case sensitivity in the first place.
