No one has done TEA yet (on the main branch), if that's what you're
asking.

The details are foggy in my brain at this point.  I remember looking
in some detail at the TEA branch a year or so ago, and being concerned
about some aspect of how the TEA branch interacted with device
selection.  I remember there was discussion about it at the time, and
I remember being personally convinced that a better solution was
possible, but by now it has been so long since the discussion that I
cannot remember the details of the problem or of the discussed
solutions.  

I have some TEA work ahead of me in my day job, so it is possible that
I will become engrossed in the whole thing sometime this summer/fall,
but it hasn't percolated to "top priority" quite yet.

BTW, you are welcome to selectively integrate things from your list
below, into the main branch yourself, if you wish.  IMHO, part of the
problem with the TEA branch is that too much happened on it.
Reviewing the changes between TEA and main, is too big a task.  If
the first two items depend on the TEA integration, perhaps you could
just take the bottom three, and move that out of the TEA branch and
into main (assuming they are suitably mature for production use by the
wide world of PLplot folk).

I'm a big fan of named branches, for focused work.  But if the TEA
branch has roughly 5 major tasks all within it, I think that results,
on a purely human level, in an impediment to getting it merged.
Especially if the merge is left to others than the developer(s) on the
branch.  It seems to me that perhaps some of this could've been done
directly on main, or that perhaps a few named branches, each with more
limited scope, could've been employed.

Actually moving over to TEA, is probably a substantive effort, and
surely deserving of a named branch.  But the rest of the stuff, I
would think, should be pretty independent of the TEA work, per se.
