But what the core team has done is provide a pretty stable interface for
getting to that point. The extension interface is well documented and
quite stable IME. If the pl/java project can't get it to a point where you
can make && make install, then I don't see what would possibly benefit from
getting into core.

But if they get to that point then it can be on pgxn and you could install
it with a pgxn client installation tool that would make things easy.
