[Data-modeling] /lang/de vs /en/german_language

[Tom Morris]

These two got flagged for merge recently which reminded me that I've
been meaning to ask why there are two parallel sets of language
definitions.  The /type/lang topics appear to be used internally for
things like tagging strings and users languages, etc, but semantically
it appears to be identical to the topics which are typed
/language/human_language.

I imagine that the /type/lang languages were needed for bootstrapping,
but are they still needed.  If they are, is there a way that they can
be hidden or made less visible as well as locked so that people don't
try to add the /language/human_language type to them (as happened
recently to German when someone picked the wrong one).
