If you do this, please also update the default PM CSS to preserve (roughly) the current look. The appearance of bullets in nodelets like Find Nodes is probably an improvement, but I don't want to force every person to individually restore the compact nodelets to being compact by hand -- you should do that for them if you want this change.
Note that requiring cabal members to use a browser that supports CSS doesn't bother me. But if this made PM look a lot different (not in a good way) for people w/o CSS support, then I'd be against it.
