No min-width support...still...

So the IE developers keep saying that they'll support more of the CSS2 spec (yes, CSS2 - we have no fucking hope of getting any CSS3 in there for a while), but they haven't put min-width support into the betas yet. Still. Min-width and min-height did not suddenly spring out of the fucking air! Why so long to implement these things? I feel like I should consider myself lucky that IE6 supports things like anchor tags.
