Also got an email but interestingly the most populated group I'm a member of has 4 users in it including myself. It did mention that my "top-level" group has reached the 5-member limit but it references a numerical ID that doesn't match my user or any of the groups I'm member to.

There may be a glitch with this rollout.

Yeah, I got the same email. I am in one group, and that group has one other person in it.

I'm in exactly 0 groups, never been in one, and I got the same email.
