should min/max for alpha-numeric cases be case-insensitive?

Question

I am having a hard time coming up with a use case in which case-sensitive min/max parameters make sense and several solid cases for a case-insensitive min/max.

Example:

With case insensitive min/max:

an exact match on /users could be accomplished with min=john&max=john

Currently, for this case, min=john&max=JOHN seems to work, but it is possible for other values to sneak in there requiring a client side post filter.

Done.

Observe, as I filter out all the Jons, Johns, and Jon Skeets in the system.
