Besides BPM/Stops, I think it would be a good idea to add to the spec a standard specification for new timing classes featured in Stepmania and recently osu!mania:
Initial proposition would be to { Time: pulse, Value: pulses_to_skip }
for Warps, and adopt the stepmania initial value, final value, start time and duration specification for speeds and just use the multiplier for scrolls.
