The TVC hardliners don't include the VOTC/VSTC figures as a part of the VTC collection because they don't have TVC numbers, even if they were on Vintage cards and really were the precursor to the TVC line itself. I don't keep track myself because don't collect packaged figures, but for sure the original Star Wars card Han, Luke, Leia will all need redone/rereleased in the TVC line to complete the 96. I'm not sure what the position is on Threepio, he has only been on an ESB card so far, right? Artoo and Chewie made it out in TVC on Star Wars cards in 2019...I don't have a vested interest in keeping track, but the people who do have list that they are ticking off from what I understand.
Judging by General Lando, Endor Luke, and Stormtrooper Luke (can't think of any others off the top of my head) the POTF card is not necessary for the figure to be counted as a good enough update to check off the figure as done for the 96. The Imperial Gunner is a sticky one, since he was issued on a Rogue One card. They might call that one a "needs to be redone."
It just seems like there are still a lot of figures to go to have the 96 on TVC cards, and many many many of them will be reissues of figures from the last 20 years. There is just a handful that can be classified as "never updated from the Kenner figure." Greedo, IG88, Bossk, Scout Trooper, Hoth Han need reissued from VSTC. Lots and lots need pulled forward from the modern era. Sticky points like "does the FX-7 mold from POTJ still exist? How about 8-D8 and EV-9D9 from POTF2?" make the prospect of recarding all these things muddy at best. New tooling is hard to come by these days, my mouth waters over the prospect of a new Hammerhead sculpt or Amanaman, but do we really want it used for another General Madine or 2-1B?
