It's a decision to spec a feature that can never be guaranteed to work. Not
only can a point in time in the future move, but how can you peek ahead,
when my hand hasn't played that bar yet?
Certainly plugins like this can work in non-realtime settings. As long as
we concede that, it is simple enough to spec that a plugin must identify
it's own additional latency.
