It could be used for xx.wikimedia.org sites as a supplementary RC page (beside
the existing one for the site's RC).

If both will be implemented the functionality should provide the same options.

I had requested something similar a few months ago. I'm monitoring pages on
both the French and English Wikipedias, and it would be convienent if clicking
on the 'my watchlist' tab gave me changes in both.

Changed component to "RecentChanges"

This is unlikely to land in MediaWiki core as it requires a lot of logic on the client-side to know about what different wikis exist, how they are configured. As well as some entry point (either MediaWiki API polling or perhaps RCStream-based).

This is the kind of thing an extension would provide. See bug 66177 for example.
