There's a long-standing issue record in the translators repo  and a PR in the main repo  for enabling the seeAlso functionality in translators. The PR didn't get much attention since it was submitted back in April and I wonder what's necessary to move it forward.
I happen to need this functionality for a translator change I'd like to
propose, that's why I'm asking, and I'm also ready to take care of the PR even if the original submitter isn't interested any more (it certainly needs at least a proper rebase). I
haven't personally analyzed the proposed approach, plus I'm not familiar with Zotero code [yet], so a comment or review from someone who does would be quite valuable, and I (or the original PR author) could take it from there.
It looks like the relevant part of Zotero code was simply commented out at some point, without any explanatory comment attached, and was never reenabled. There was an earlier PR that tried to simply uncomment the code, but AFAIU it's not as simple as that, and the PR I've referenced adds more logic, but I just don't know if it's correct, and simply needs maintainer attention to get merged, or a rework is required, so would be grateful for a comment.
