Webkit Dev (speaking to Webkit Program Manager) -- Hey! I've figured out a way we can give divs rounded corners.
Webkit PM -- That's cool, what do you call it?
Webkit Dev -- Well, for the bottom right it's "border-bottom-right-radius"
Webkit PM -- Cool.
<some time later...>
Webkit PM (to Webkit Dev) -- Hey! I just got off the phone with Firefox PM. He says they've also developed a way to give divs rounded corners.
Webkit Dev -- That's cool! I guess it was a needed feature.
Webkit PM -- Yeah...only problem is the name. They decided to call theirs "border-radius-bottomright".
Webkit Dev -- Oh.
Webkit PM -- Sooo, yeah. If you could just change that name.
Webkit Dev -- But we already GM'd the build with that name in it. To change it we'll have to back out of the GM, requalify the build, change the documentation, send out new seeds, redo internationalization, send it back to QA, and declare a new GM. That will push out the release by 3 weeks, and besides, I have 20 bugs in my current backlog that are completely unrelated to border radii. How important is this?
The problem is that neither vendor is willing to solve it in one hour. They want to get their own way. It's simply arrogance.
