Can you explain the motivation behind this change?

[dnoneill]

@jcoyne I have updated the comment to include catkeys that aren't working with how the code is currently structured. This is in relation to issue 3754. I am guessing with the folio migration the old fields aren't getting written correctly but I am not an expert on how the code is structured. Cory definitely had the same worry about this change which is why it was pushed up but I am not expecting it to get merged immediatly. I just opened a PR so it wouldn't get lost in the branches.

@dnoneill could we set this PR to draft until we've done further testing/analysis?

I don't think (titles.jsonb ->> 'instanceId')::uuid is an indexed column in the FOLIO database, but maybe/hopefully that changes in a new FOLIO release.
