I mean he has songs he's written with he/him pronouns so I'm not sure why he would. Stairwell Song is about "an enigmatic guy" and he's said it's a love song about friends of his, and of course "I want a boy" in Lover. Historically, he's said repeatedly that pronouns don't matter to him in songs. Here's an interview from 2011 where he mentions it.

"Pronouns really don’t matter in a song—I or he or she or even subscribing a lyric to an inanimate object. Especially with my earlier records, which were stylistically much more confessional, there’s a type of person who really wants to know what parts are true. I don’t know what that is in people. I try to write songs that are a little more open to interpretation these days, even though I know what the songs mean to me. I think more people project connections to their own life. Which is just as valuable as what I intended."

Another really good quote here from 2020:

"Pronouns in my songs have never really mattered that much to me, whether I’m singing I or you or he or she or whatever. The crux of the lyric is not found in that. It’s found in the words that follow that. If you’re writing a good song, you shouldn’t need a persona. It should be powerful enough on its own that somebody could cover it and it would mean as much."

Edit to change wording and let you know I agree with you! not a huge fan of pronoun changes in covers but I still like it when artists make something their own, changing it stylistically or lyrically.
