That's logical. I made an implementation of that for the 10.4 metadata-aware tools (a simple ">=${VER}") which I imagine would work for other fields. More intricate version details could be implemented as foot-notes similar to what's there.

Well, "Finder" metadata (which I've seen referred to as "Finder info", too) is essentially the metadata available via the SetFile/GetFile tools. That is: creation date, HFS+ attributes and type/creator. I'd think the SetFile/GetFile "modification date" is the same as mtime, but I'm not sure on that one.
For non-definitive yes/no cells I suppose there'd be a short description or perhaps a footnote (as some of the existing exceptions). In the same way versions could be noted, too (as above).
I was optimistic for the listings, however. For example you have to specifically configure a Bacula option in your file set before it will pick up the resource forks and is easy to miss.

This makes great sense and in fact I considered doing that first or as a follow-up. I think I hit the major ones, though (metadatums, that is :). If I started that page (or amend this one) would you contribute what you know?

There is probably no tool short of a sector-level copy (dd) that can perfectly capture everything :).
