I haven't tried, but don't you get this if you copy a workspace built that way
to a tag (with all the downsides of doing that, like not necessarily having any
other history of files there)?

Why? Externals are a better way to get sub-components, but they should point to
tagged copies.

The problem here is not so much not being able to create the tags you want but
the time that you let the libraries (externals) float pointing at their HEAD
revisions. A cleaner approach is to tag the sub-components at 'release-tested'
points, make a release branch of the main code where you peg the externals to
the appropriate tags, then create QA and release tags from the branch. This way
additional changes can be made anywhere in the project or library trunks without
affecting your current builds and release and the final tags are created atomically.
