I think that's one decisively in the "thumbs down" column. Pity we don't have a
reaction mechanism to indicate that ;-) ;-)

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

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.
