Well, except if
- you've pruned
- the importer never imported anything but the most recent one.
One thing that _might_ be a good idea for tags (if people _really_ want to
actually update tags under the same name) is to have a "parent" pointer
for tag objects, the same way we have for commits. That way you could - if
you really wanted to - create a chain of tags, and show the history of
them.
Now, I personally think you'd be better off just having separate names,
but for something like a "passed testing" tag, it might be valid to (a)
have the last one and (b) have a history chain. And it's not like it would
be technically "hard" to do.
I dunno. Personally I'd rather try to just tell people to not re-use
tag-names, because it kind of destroys the whole point of a tag ("I
checked out tag X!" just leadsto "_Which_ X?").
And you could certainly do the "passed testing" thing with commits in a
separate branch instead: you'd create the "testing" branch, which is
always a set of commits that have as their primary parent the commit that
got tested, and as the second parent the previous commit in the "testing"
series).
So _generally_ I think we're better off keeping things the way they are,
but on the other hand, if only to work well with idiotic systems that
mis-use tags in ways that tags shouldn't be used, we *could* just extend
on what tyou can do with a git tag too..
