Sure there is.  A generically named function on a fancy/schmancy
system should do the correct locale-dependent operation when case
mapping is requested.  It should also provide a "neutral" locale which
will implement the locale-independent case mapping from the Unicode
data files.

Yep.  And the exact contours are unknown.  I'm not asking for nobody
doing design; I'm asking for nobody doing design while they are doing
standardization.  As long as the functions do not rigidly require
specific behaviors that are known to cause problems, and are not
misleadingly named, I'm content.
