Not interesting for at least two reasons.
Why are "tags" any special? "git branch --delete-merged" may also
be of interest, and for that matter "git update-ref -d" to deal with
any ref in general would be equally valid if such an option were a
good idea.
What you want is a way to compute, given a set of tags (or refs in
general) and a set of branches (or another set of refs in general),
find the ones in the former that none of the latter can reach. With
that, you can drive "git tag -d $(that way)".
In other words, the feature does not belong to "git tag" command.

Again, not interesting. You already have:
git for-each-ref --format='%(refname:short)' refs/tags/TOKEN\* |
xargs -r git tag -d
