You haven't missed anything.  I think we're a long way off being ready to
make a final choice between FDs and TFs.  For one thing neither of them
is standard, and both monads-* packages also require other non-standard
extensions.

But we are at the point where we can decide to make FDs optional, though
that hasn't been decided yet either.

That's not to say that the HP shouldn't present a pre-packaged choice
(probably FDs for some time), just that it shouldn't get in the way of
alternatives.
