The change _does_ exist in the tag. That is, the tag does
not exist until the snapshot of the workspace is committed.
If you want that copy you use the tag and what's in the
trunk is not particularly relevant. As you noted in your
example, someone else can modify the trunk any time so you
can't trust what is there unless you have a revision number
you know happened as a commit from a workspace in exactly
the right state. So why not use the tag committed from
there instead and let the trunk go about its business towards
the next one? If you want the change on the trunk for future
versions, commit it there too, but there is no need for that
step to be atomic with anything.

But that's what you get when you name this tag. What is the
problem with using this tag name anywhere you might have
used a revision number or the label that you'd like to
refer to one?
