feedback from others on the point.

I'll amend your assessment: I think this would be /extremely/ overengineered.

Specifying mechanisms for highly nuanced behavior is worthwhile when there is a well-understood problem, widely viewed as being substantial, and therefore, there is good motivation for adopting the added complexity.

Most of the time, enhancement mechanisms, like this, already have significant adoption barriers. So keeping them as simple as possible is to be highly preferred, over making them more nuanced.
