It’s only a tactic for the edge case where someone presents ambiguously, in which case they’re probably perfectly used to it as a way to politely ask. And yeah, it’s a little awkward, but no more so that any other “polite chat with a new person” banter.
You can usually tell what pronouns to use via normal social awareness, and when in doubt, sharing yours is a polite way to prompt others to share theirs.
