This is not something I or anyone I know wants enforced by policy or "if you know what's good for you." It's nice and helps normalize the practice for people who need that acceptance, and it stands out in a good way, but the lack of stated preference isn't a negative indicator.

Now, when someone flips out on me because I default to they/them in text when someone has no stated preference and there's no way to tell, that's a negative indicator. It's clear they have a preference and refuse to state it just to be difficult. But it's a rare occurrence.
