The simple solution would be a virtual :
    GOService::unloadable_p
A plugin is unloadable if all of its services are.

An interesting design to consider for the future is to support in
place reloads.  This is very useful for rapid application design,
but is probably somewhat unique to spreadsheets.  The goal being to
allow a user to remove and reconnect a new version of a plugin
without restarting.
