Well, it does seem to be the only way, short of inventing some other
way of a plugin to contact "something" entirely outside the host
process. That would still mean that the plugin has to use non-host
services to get the job done, but at least, it wouldn't do GUI stuff
from within the host thread...
For all practical matters, I don't think there's much point in trying
to "fix" this - but some thought should be put into avoiding that the
plugin pops it's window up whether it's appropriate or not. (Loading
a bunch of plugins doing this into a host that's supposed to
configure the whole plugin net from a net description file would
basically not work...)

Doesn't sound very user friendly to me...
