If we must set a blanket policy for MediaWiki, I think
it should be pretty
general, something like:
* *current* release of all major browsers with 'evergreen' releases

* a chosen *subset* of major versions of IE
* a clear expectation that some advanced features won't work with some
versions of some browsers, and a sane policy for acceptable fallbacks?
Safari is a bit complex, because Apple forks stable branches for
different versions of OS X, so it's not quite an evergreen browser.
*But* these stable branches sometimes have significant back-end
rendering functionality quietly backported into their point releases.
That can make assuming the latest version of the rendering engine is
everywhere close to correct, but not always. The currently maintained
branches are 5.1.x (OS X 10.6) and 6.x (OS X 10.7, 10.8). The 5.0.x
branch (OS X 10.5) is definitely on an older rendering engine, since it
hasn't had a point release since 2011; its market share is declining but
still has around 10% of Safari users.
