I have not checked for opam, but it reminds me fixes in other importers.

5278cab3dc * scripts: import: gem: Fix recursive error handling.
7229b0e858 * import: cran: Return multiple values for unknown packages.
1fe81b349c * import: elpa: Return multiple values for unknown packages.
6bb92098b4 * import: hackage: Return multiple values for unknown packages.

And the bug#44115 report [1] mentioned opam but indeed the fix probably
fell in the crack. :-)

Do you want to give a try?
