Before we make fun of the webkit folks for not doing the proper work because "it's too slow," remember that these are the same folks that we praise for making the fastest dang HTML rendering engine on the planet. (Or near enough.) Their culture of performance has significantly raised the standard of web browsing performance, and that's not something to take lightly.
I imagine it would have to make a fairly significant difference in rendering quality in order to make any speed losses worthwhile. Death by a thousand cuts and all that.
