Hi,

There may be another case not covered by my reading of the above rules.

Consider this situation:
- there is a primary issue for release 17 and a corresponding CSR
- there is a backport for release 11 and a corresponding CSR that is marked for multiple versions: 8-pool, 11-pool, 13-pool, 15-pool
- A PR is created for a backport to 8u

The search for a CSR matching the current 8u backport, has to search all of the existing backports for such a CSR request.
