This is where dropping Windows support may harm Safari. Yes we can test against webkit via Chrome now so in theory anything that works on the current PC trinity (FF, Chrome, IE9+) should work just fine in Safari, any bugs that get raised by Safari users that can't be reproduced in Chrome are just going to get labelled "NONREPRO" or "WONTFIX". Chrome and Safari are not completely in-step so there could easily be the odd issue that affects one and not the other.
Admittedly this isn't a big problem for Apple users so the above concern isn't a killer: they can use FF or Chrome if Safari won't cooperate (though good luck convincing some users that switching browser is a valid workaround for any given bug).
