Let me propose that we add something to sections 6.7.5, 6.7.9, and 6.7.11 like:

Addition of temporary flooding should be done with caution, as the addition of excessive connectivity to the flooding topology may trigger unwanted behavior. Routers SHOULD add temporary flooding in a rate limited manner, if not configured otherwise.

This is the addition of one link, and in particular the onus is really on the DIS to drive synchronization.  Per your above arguments, I’m comfortable with this.
