By a vote (as best I can tally) of 5 to 2, option A, or something similar,
wins the nomination. How's this sound?
8.2 Parameters and saving/restoring state
-----------------------------------------
For the purpose of saving and restoring state, the abstraction of stata
(sing. statum) is introduced. A statum is a single atomic unit of state.
A plugin's state is completely represented by it's stata. When a host
wants to save the state of a plugin (for a preset, for a project file,
etc.), the host can iterate over all the stata exposed by the plugin, and
retrieve the current values. When restoring state, the host can set the
values of the stata. Stata may be opaque blobs, which are unintelligible to
the host. Whether or not stata are actually entities in the GMPI system is
TBD. It may be decided that stata are actually abstracted from parameters,
with a common (but not mandatory) 1-to-1 mapping, or it may be decided that
stata and parameters are the same thing.

suddenly there's a big market for "Dummies" books. Cause and effect,
or merely an ironic juxtaposition of unrelated facts?
