Personally to me I have no problem with using the copy functionality for
tagging bits of the repository. It is a slightly different nomenclature but
I can easily see that it is offering the same functionality. Or is it ... ?

The answer to that is NO.

It only offers the same functionality if I have implemented an additional
pre-commit hook that prevents people from committing changes to that copy.

This pre-commit hook will also look at user entered text (i.e. the name of
the copied directory) to identify stuff that should not be committable. So,
what happens if I typo the name of my tag (e.g. /repos/tagss/mytagwhatever).
Now I have created a copy that isn't equivalent to a tag because my
pre-commit hook is only looking for /repos/tags/*.

Doing anything on user entered text is always going to be prone to error.
That is why you code systems up to perform common operations and implement
common restrictions.

File systems, for example, aren't set up so that to make a read-only file
you put it in a specific directory.

Someone mentioned locking up and coming for future releases. Hopefully this
will provide a way to make a copy and then lock it down against any changes.
