OK, you're proposing that the 'tagname' be a piece of metadata
attached to TARGET@REVISION, rather than making a cheap copy
TARGET@REVISION.

What's confusing here is that you're offering a solution to something,
but nobody seems to understand what that something is. What's the
problem you're trying to solve? Before you can propose technical
solutions, you need to persuade us that there's a problem with
subversion's current tagging system.

As someone already mentioned, why would one ever "checkout all tags"?
And even if somebody wanted to do that, wouldn't they get a ridiculous
amount of data no matter what SCM they were using?
