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.)
