@[email protected] Ah crap. Sorry you're having to deal with that kind of thing.
Is it common? Probably, although I've been out of the dating game for a couple of decades. Is it a useful red flag to let you know this person isn't mature enough for a solid relationship? Definitely. Important note though: I don't think having boundaries is the same as being transactional, and it can be worth some reflection on when certain actions are really one or the other.
For the avoidance of doubt on your examples: demanding an emotional response from you is not them having a boundary...
