Thanks so much for taking the time to explain. I was thinking more about how you compare the People section to the created project's assignments, not so much the template - do you have a method for that specific cleanup process? Or maybe you're saying that since that's so hard to do, governance beforehand is way more important for you?
One of our pain points is when someone is accidentally assigned to a task, and nobody goes into the People tab to remove that user.
this is a separate question to the original, which had to do with templates. I mention this because if you don't get a good answer here, you might want to reword your question and restate it as its own post.
You are correct though -- I don't feel as though there's a good way to indicate that someone on the People section isn't being assigned to anything in a project, and since there are a lot of projects getting created over time, you'll be trying to hit a moving target (not worth doing).
If it's required by your company, it's definitely something you should put on each Project Owner to keep clean, and because of this, starting them off on the right foot with clean templates, and providing them with the training to keep their People sections clean, would be your best bet.
