As for IE6, that roadmap is quite simple in my opinion.
At this point MediaWiki already degrades gracefully in older browsers in a number of different ways. We've put our cut off point for javascript execution in general at IE < 6 and Firefox < 4. And for stylesheets we also support IE6 for the basic layout (enough for text to be readable in a way that isn't distorted or hard to read).
In any browsers where we don't abort the javascript pipeline from the startup[1] module, there must be no fatal errors or uncaught exceptions due to browser support.
While a library doesn't have to throw an exception in an older browser per se, in case of jQuery UI it's quite simple. We can only upgrade to jQuery 1.10 when we drop IE6 support for Grade A. And when we do, IE6 will become javascriptless[1] and jQuery UI will no longer be relevant as problem in IE6.
This seems really reasonable.
Are we still agreed that Grade A means anything over 1% of readership? If so, we should reconfirm what our browser share is really like, because last time I checked, IE6 was less than 1% of total and thus eligible for dropping from Grade A now and forever (he says with great antici.........pation.)
