Make it happen.
What sould be case insensetive?
Usernames.. logins, user pages, etc.
And repository names. Generally I don't think the should be case insensetive, but forced lower case.
I think they should be all lower case for pushing/pulling (where one usually thinks "unix shell account") and case-preserving on the website while being still case insensitive.
