Ok, that's indeed what I understood, it was just conflicting with
what was mentioned above: we wanted to see servet already disabled by
default, and only enabled manually.

Ok. I was also hit by the fact that core_linux_x86 is not valid, only
one '_' is allowed.

Well, that still looks hardcoded to me. Actually, a simple way would be
to order all plugins in just one list by priorities. When loading a
plugin, one checks whether the exclusion point of the plugin was already
filled or not, and load the plugin accordingly.

You are talking about xml only, not other plugins, right? Well, I
believe it still makes sense to expose the xml ones as loadable just
like the linuxx86 plugin is, or even a user-provided plugin.
