In this case, it's deliberately non-gendered language. Lower-effort, as kalium says. In my case because I cultivated the habit, in years past.

As both you and Douglas_Knight point out, there are tradeoffs involved. In the case of not gendering pronouns I expect I’ll continue thinking it worthwhile.

But it’s a helpful thing to consider- I’ll bet there are other habits I’ve developed that I’ve never considered if it’s worth the costs. Especially when I contrast my teenaged self – “I don’t care what anyone thinks of me” + “I’ll choose my words for my own aesthetical pleasure” – with the me of today – who does care, and on balance values communication higher than self-expression. I doubt my conversational habits have shifted as far as my preferences have.

I’m also interested by what you say about details. It’s not something I’d’ve thought of, worrying I tend more to being too verbose. But I like to write, and concrete detail / description is the area I’d consider my weakest there. I can think of some ways to practice this (started playing tabletop RPGs recently, for one.)
