Oh, I see what you mean.  This isn't supported yet, but it will be.
It's just a backend implementation detail.

Well, it wasn't *always* the case, at least not shortly after Jasper
rewrote the panel (before your time, IIRC).  There was even a
discussion on xfce4-dev about whether or not the panel should remove
config files after a plugin is removed, and I'm pretty sure it was
decided that it shouldn't -- guess that decision changed.

Regardless, I've added a RemoveChannel() method, so...
