Comment (by simonpj):

 I don't really care either, but my inclination is that if it's something
 we expect GHC-API clients to call, it should be exported by GHC.

 You want `runTcInterative`, but presumably to make use of it you also need
 some other functions in the `TcRn` monad.  So probably it alone isn't
 enough. Identifying a useful set would be a Good Thing.
