Thanks for the detailed explanation.

Option 1 might be the only way to go. Adding end-points for tags would just
increase the API without any benefits. Since the output is identical, tags
or ids is just a query parameter. Also, we need to think about backwards
compatibility and expectations that we already set. We already have APIs
that support both, so we need to continue that path.

For making these changes, I would break your proposal into several PRs and
Jira tickets. A single massive PR will make the review process more
difficult.

Thank you,
Stefan
