  Mostly.  It turns out that the TEAP RFC is incomplete, and can't really be implemented as-is.  Jouni Malinen has some updates to fix things, but I'm not sure if anyone else has implemented the same fixes.

  We have a lot of future plans.

  TBH the fastest way to get TEAP in is for someone to implement it.  It's 90% like EAP-FAST, so just copying that code and editing it would be a good start.

  The issue for us is that we have a long list of work items right now.  If TEAP is either contributed, *or* there's a strong demand for it, we can take a look at the list.  Otherwise, it will remain a "wishlist" item.
