What's on your mind?

WoW frequently "reimprints" old items with new current stats. For example, you can have found an item in an original expansion, or have found it while doing a "time warp" dungeon several expansions later. (In this discussion, I call this new item a "variant" of the old one.)

We should explore if it's worth detecting these variants and adding/replacing the tooltip with the new variant info.

Challenges:

1. What APIs expose if an item is a variant of another?
2. Are these variants present in Classic and Vanilla? If so, are the APIs present in these versions?
3. How do we expose variant info? Do we have an options setting? Do we replace the original data or just add to it? Etc.
