A lot of emails get casefolded no matter what. This is enough of an inconvenience that nobody in their right mind would operate a case sensitive mailbox you would be using for account signups.
- Piskvorrr 6y agoA lot of people are still using that part of a regex no matter what - I still run into this regularly (and have been, for two decades now).

This is EXACTLY it. Both in the local part, and in TLDs - nothing clever about people being too clever by half, and generating false negatives on their input side.
