The English Wikipedia now has links to `Special:MyContributions` and `Special:MyTalk` for IP users via `MediaWiki:Common.js`:
This implementation is rough as there's a flash in the page rendering when the underlying links from MediaWiki core (Special:UserLogin?type=signup and Special:UserLogin) get appended to. If we want these links for logged-out users, we need to do this server-side.
We can probably re-use `$wgShowIPInHeader` for this functionality.
I'm still not totally sold on the virtue of having these links for logged-out users. I'm personally still mulling it over. But if it's to be done, it should be implemented without that awful flash. It's super-annoying and it's currently hitting the majority of visitors.
I thought we'd also removed the little person icon from the personal tools bar, but this change seems to re-add it. We should investigate that as well.
