Assuming that no webpages are reliant on those bugs, sure. One of the problems with everyone targetting a single rendering engine is that they become reliant on the bugs of that engine, to the point that it becomes difficult to make any changes without breaking compatibility. Look at IE, for instance, especially the IE7-compatibility mode in later versions which wasn't IE7 compatible.

Hell don't look at IE, look at Windows, Windows guys had to rewrite a CORRECT implementation of logic check if SimCity was running and turn of a special flag to run the old version of allocator.

Now multiply that story for every badly written WebKit site that relies on some backward ass crazy bug that no maintainer sees fit to fix.
