I don't find this over-compensatory at all. If people are trying to validate you, and make you feel welcomed, why demean that effort? As a transgender man, I *know* that I use gendered terms more toward transgender women than toward cisgender women, both as a form of validation, and as a way of making it clear to anyone else present how I expect them to treat the woman I'm interacting with - it's half validation, half boundary-setting. I've also been on the receiving end of this from other transgender people; the only time I find it irritating is when other transgender men use "bro-ey" terms like "buddy" or "dude" because I find it juvenile. "Mate," is probably my favorite gendered term, "man" is almost as good. These are just my preferences, though.
