Agree on the emails (even just from mobile devices having a habit of putting capital letters in unintentional places), but I was more meaning the attribute keys, eg "username", "familyName" being case-insensitive. I'd be happy enough with any casing convention here, but would prefer one case sensitive one.
I suspect in practice most systems just use camelCase, but they could use TitleCase / ALL CAPS / etc which bugs me as it feels like a committee couldn't agree and decided "why not all of them".
There's a good chance there's historical context I'm missing, though I'd like to imagine any SCIM V3 might have stricter rules on that kinda of thing to reduce implementation complexity
