I think you are correct. I am in the same boat. Consistently, if I send emails to myfirstnamemylastname@gmail.com they are delivered to me. Without fail. I too registered in the beta phase and I do not think anyone has an account without or with more periods than mine. The type of messages I receive are typically one of things like hotel, reservations, e-commerce shopping receipts. Likely someone misunderstands the address or misses a letter in between. Maybe alerting everone from myfirstnameAmylastname… to myfirstnameZmzlastname@gmail.com helps them take better care.
