Noting in passing, in doing T185948 we touched a lot of different code points in MediaWiki core that provide a "user comments on action" field, and there's quite a lot of poor uniformity:
It'd be nice to not just use OOUI consistently, but have the same input widget in some ways for all of these, I think (albeit with different lengths, perhaps).
