This seems to do nothing to address the issues I raised in https://meta.codidact.com/posts/283073#answer-283073 and also raises another issue, namely that categorization via tags (because especially, but not exclusively, abbreviations) can mean very different things to different communities and in different contexts. As an example that has no home on Codidact currently, try getting a pilot and a train driver talking about the role of "ATC" in their respective fields and watch confusion abound.

I had not referenced your post at the time, I was considering the split of video games into a development and games communities. Though I will clarify I think you'd want something separate from the current tags. it would behave a lot like tags, but would be it's own separate thing.

Culyx‭ I'm not much of a gamer, but I struggle to think of a question that would be equally applicable to someone playing a video game and someone developing a video game. Still, if you have a reasonably concrete, solid suggested use case for when this feature would be useful, keeping in mind that communities are disparate but likely have overlap (e.g., game developers are likely to be interested in gaming questions in general), that would make it much, much easier to discuss your suggestion.
