My only take on this is that the XML file perhaps should compilied in so
that the XML spec for the layout is known to match /that/ version/build of
the plugin.

No,no, not good idea, I think is should be up to the user to select which
interface they want to use with the plugin.
Though I don't see why *ARDOUR*, when IT loads the plugin/gui should not
check whether:
strstr(read_tag("/ladspa-gui/plugin1/gui1/header/suggested-app"),
"Ardour");
and set that gui as the default if it does...not that the user shouldn't
be able to select some other gui /if/ they so choose so.
EG: a mixer plug gui with pots, rather than slider.
