It's still optional if init is supplied, and that's idiomatic for our
newer plugin interfaces.  Obviously, if a module supplies init and not
fini, it has no chance to clean up memory allocated by init, but perhaps
it doesn't need to do so.

Perhaps, but it's not obvious where to put it.

Yes; I will change that.

No, but I already have a note to do so before pushing this to master.

Thanks for the review.
