Basically, we have no information about what the proper parameters of external
languages would be. (We have some pretty good ideas, but that's not the
same.) Especially if we override the trusted/untrustedness, we could create
complete disaster.
Ultimately, as we add more loadable facilities (languages, plugins/modules,
foreign-data wrappers), we will need a better upgrade mechanism anyway than
maintaining our own override list of everything in the world. So let's just
leave this mechanism restricted to the built-in languages for now.
