I feel like it’s a courtesy. That said, I generally give people their preferred pronouns. It’s very much expected in professional settings and I work in HR so I don’t really feel like I have much choice. In personal settings, I’ll do pronouns too, although I’m not perfect and can make mistakes if those aren’t the pronouns I would naturally give someone (based on their sex) or if they are non-binary or unusual pronouns.

My personal opinion about pronouns it that they should be based on sex though (or perception of it). I feel like trans people should earn pronouns through passing rather than expect them or ask other people to use them. Using pronouns that conflict with how you naturally see someone takes effort and I’m not sure if it’s fair to expect people to do that (even though I do it myself). The only time I think sex-based pronouns are silly is when it takes mental effort to use them. Like if someone naturally reads as male, but you know they are female (or vice versa), I don’t believe you should put effort into misgendering them and I feel like people who do that are just being mean.
