Why don't more designers contribute to open source?

Genuine question. A lot of open source projects have solid engineering but rough UI/UX: inconsistent layouts, confusing flows, basic usability issues that a designer would likely catch quickly.

I'm curious about the reasons behind this. Is it that designers don't feel welcome? That there's no clear way to contribute design work (most workflows are built around code and PRs)? That maintainers don't prioritize it? Or something else?

If you're a designer who has contributed to OSS, or a maintainer who has worked with designers, I'd love to hear how it went.
