wheel events are a big problem for scroll performance. Eg. using timestamps to monitor latency@n8schloss has found that wheel listeners are a real problem for scroll performance in Facebook. There are a number of incubation-style efforts underway to try to improve this, which if successful should probably make it back into the UI Events specification somehow.
In particular:
When all wheel listeners are passive, wheel events should be uncancelable (already shipping in Chrome and I believe Safari and Firefox). Eg. perhaps UI Events should have a "cancelability" section like Touch Events does
