Simplicity. Both from the point of view of the host and of the user (1
file corrispond to 1 plugin => easier to remember where a plugin is).
I really don't see the advantage of having multiple plugins in a file,
except for the reason of having many plugins doing the same thing, but
where controls are once streams and once single-events (see for example
the plugins in the LADSPA SDK).

Anything. For example the start and stop of a sequence in a sequencer
plugin, the start and stop of a sample in a sampler plugin, etc....
Having a general purpose standardized trigger allows easier and more
flexible interconnection between modules (i.e. plugins).
