Damping notes on a percussion instrument is quite
a normal thing to do...

Apart from this, MIDI is very keyboard-centric,
and it shows in all sorts of ways. For example,
on any channel, note-on events are identified
only by their note number, so you can't have
e.g. two independent events of the same frequenccy.

I guess many synhts that have limitied polyphony
use the note-off event in the voice assignment
algorithm - if not the patch has to tell it when
a note has ended and the voice can be re-used.
So they may depend on it.
