Well... patches are welcome! I don't have a detailed plan for further
libtiff development, but I shall post here some proposals right after
final 3.7.0 release (it should happens at this week end).

But for me the BigTIFF is the most important thing among other libtiff
improvements ;-)

You can read and write arbitrary tags without non-image IFDs. Those IFDs
used to store the arbitrary (often vendor specific) data. I'm wondering
what kind of data you want to embed in your TIFFs if the usual tags are
not enough for you?
