So long as the question is specific in what plugin the user is looking for, I don't see a problem, other than the fact that it is asking about a game.
I was reading this meta question but I wasn't sure what the line was between asking for recommendations for a game, and asking for recommendations about a game.
I think the answer is already in the linked question:
What editor for [GAME]” is a software recommendation that happens to be related to playing games — again, that's for-a-purpose software, so it's fine.
and
A question asking what OS is most fun to debug would not be. Conversely, a question asking about Minecraft or Kerbal Space Program mods for worldbuilding would be on-topic. The distinction is not the primary purpose of the software, but the primary purpose of the recommendation.
(emphasis mine)
If I'm not incorrect, I believe that a plugin is even farther away from a mod for a game - and thus it should be on-topic.
Whether or to what extent games are on-topic are still being debated. However this case appears to be uncontroversially on-topic. From my answer, which is rather towards the anti-game side of the spectrum:
“What editor for [GAME]” is a software recommendation that happens to be related to playing games — again, that's for-a-purpose software, so it's fine.
As long as the purpose of the software is to accomplish a concrete task (as opposed to being entertained), it's irrelevant that the concrete task happens to be related to a game.
