I concur. By the way, my source is on my site (http://abiword.pchasm.org/builds/)
periodically updated as I make reasonable progress, in case anyone wants
to look at it. At present the interface/API is still subject to
changes/cleanup, so its not ready for general use yet. Later this week
I will try to get some of the importers/exporters done. Today I've
gone through and tried to figure out what was causing memory leaks
(per the debug dump at AbiWord.exe exit), which it ended up being that
the plugins were never unloaded, so they didn't get a chance to cleanup.
I'm going to apply a fix shortly, without which trying to use the
link-grammar plugin will make AbiWord appear locked on exit in a debug
build as it tries to show all the memory never free'd.
Once my API is stabilized enough and I have a chance, I will add some
documentation for using it.
What are your ideas [API you've been considering] for supporting importers
and exporters?

I'm trying to follow your commits, as I do think in the end the best
support will probably be a combination of what you are doing and a
little of my stuff. Load order isn't an issue for me, presently
AbiWord loads the plugin as usual, which has no imports from AbiWord
so that goes well, AbiWord calls the plugins register function, which
then in turn explicitely loads my AbiCapi plugin, which causes it
to be loaded and it does has imports from AbiWord so Windows goes
ahead and resolves them [at least I think thats what happens].
Now that I have it so it does unload them, I need to check to make
sure the unload order doesn't actually make any difference.
If it does, then I'll will probably make my AbiCapi plugin just a
DLL [which works fine, just doesn't give it a chance for one time
[de]initialization].

Anyway, I'm just having fun playing with the plugins.
