I suppose I do find it annoying on others' behalves when women in hijab or niqab are asked for their Christian name at work. It's thoughtless imo and I don't think that phrasing is used much anymore, given name is more likely now.
I also know that the two women in the team who are now giving their pronouns in their email are not bellends. What does scare me a bit is that they are language impairment specialists. My view is that for me to ask people with aphasia to use any specific pronoun, even if obvious, is adding unnecessarily to their linguistic burden. And I don't think they give them to patients, only other staff members. Which doesn't feel very equitable or partnership focused.
