generally lgtm however there's a more complex problem: it should only show up if it is set or the labs flag is enabled. I'd generally recommend just holding off on this instead and waiting for it to leave labs, doing it then.

Ah, I grepped through the code and couldn't find the labs setting for it so presumed it was released already

It's under "feature_pinning"

Wow the roles tab looks ugly these days. I guess that needs a design

Thanks for making this contribution a while back. Since the code base has changed since this was opened, it no longer applies cleanly, and I don't think there's a need to keep it open in this state, as we can always find the code here again if needed. If you are still interested in pursuing this feature, please discuss with us in #element-dev:matrix.org to find a good approach forward.
