"Just sufficient" depends on purpose. It also depends on the elegance of
the interface. Protocols found insufficient: MIDI, VST. Protocols long in
use yet still not found insufficient: SQL92, TCP/IP, XML. A simple
interface with a high degree of data abstraction is what we need. This is
not inconsistent with efficiency.
Again, I feel I started this discussion down the wrong path by complaining
about inadequate implementation assumptions instead of incomplete musical
use cases and vague requirements.
How do you propose satisfying the use cases I have mentioned: plugins that
generate accompaniments for recorded sequences with "feel", plugins that
process and generate streams of events in synchronization with the host,
and controllers that are bound to specific notes of specific voices?

Thats a very sweeping, and to my mind not very accurate statement. I think
APIs that are just sufficient have a better history than those that
attempt to be all-encompasing.

A lot of this stuff will be host-specific, and just irrelevent. Its likly
to lead to the "plugin A works in host X, but not host Y" syndrome.
