Not at all.

The ALSA sequencer API is an interface between multiple drivers and
applications. Adding a feature to the interface will not have any
measurable effect because no other application will use it.
The time of an event is the time at which it is actually delivered.
If you want to be compatible with most other applications, you have
to deliver the events at the desired time.
