So when will we be able to drop IE6 support in MediaWiki completely? What metrics/thresholds can we use?
IMO there's a difference between no longer supporting IE6 and no longer protecting IE6 users from XSS attacks.
I would suggest to set a percentage of worldwide usage as reported by some "trusted" statistics reported, or possibly a percentage of Wikimedia pageviews. 3% or 4%?
At least for JavaScript feature development, our unofficial cutoff for "we're not gonna spend any time on this browser, if it works, great, if it doesn't, tough luck" is 0.5%. However, that's just for JS enhancements; it's my opinion that at least reading Wikipedia should be possible (i.e. not severely broken) in almost every browser.
