Not really. In GURPS, like Call of Cthulhu and many other non-D&D games, there's not a lot of change from version to version. For rules wonks, answering for D&D 1e vs 2e vs 3e vs 4e is a completely different thing. For many of these other games, it's a lot more correct to say "I have a GURPS question... It's 4e if it matters, but it's not likely it will." And that's what that tag combo is saying. We don't have federal reporting standards dictating everyone disclose their exact rules edition, the point is to scope it's domain to get the right people to answer in the desired scope and to facilitate future find ability within that scope - they are doing that fine and I fail to see any bad effect justifying mass intervention in those questions.
