It's not necessary, but it's a very useful convenience. It also allows the
UA to perform transition effects that are impossible just at the author
I think Simon is already pointing out potential gotchas. What exactly is the

Nothing; see the proposed UA style sheet additions in the spec.

You can't do it as well as the UA can, because a really good transition
effect involves desktop-level effects that authors don't have access to. For
example you might want part of the window to zoom out and cover the entire
screen, semi-transparent over the desktop while zooming.
I would disrecommend authors trying to create custom transition effects that
depend on geometry; they probably won't work across browsers because they'll
interfere with the UA's effects.
"Now the Bereans were of more noble character than the Thessalonians, for
they received the message with great eagerness and examined the Scriptures
every day to see if what Paul said was true." [Acts 17:11]
