I've told this story before, but I had Campagnolo 8 speed indexed DT shifters and a Shimano 8 speed hub/cassette and a Campy 8 speed RD. I had purchased a Shiftmate for that combination, but forgot to install it. It shifted fine, although by the specs of cable pull, sprocket spacing, etc., it really shouldn't have. I didn't even realize I'd forgotten the Shiftmate for a few hundred miles and was very surprised. I later completed the project by building a wheel with Campy 8 speed hub and cassette and it still shifted fine. Better? A more astute person might have determined that, but for me they both worked - crisp, accurate shifting, proper range up and down, nothing clunky at all.
Agree. Good used ones are inexpensive and are rarely worn at all if you're just a bit discerning, in my experience. And lower tier new ones work great and aren't expensive either.
Derailleurs are relatively cheap. Not a lot of reason to mix and match once you've spent the big money for the brifter.

The ST-7400 first hit the Shimano catalog for the 91 model year (catalog page attached, note the arrow on the FD arm). Protos were around earlier but no info on what they were like. If the protos uses the same pull as the commercial model it would have used some type of shorter arm FD. If it used the older long pull FD, it would need a larger cable take-up spool or longer 'throw'.
The other brifters did use the shorter pull and new FDs, my point in my prior post about why the change was made. Reread my reasoning for the change in FDs.

Once the spacing gets closer, like 9 or 10 speed, you'll see more issues trying to get one to index on the other.
