But I can't see how this behavior makes sense for the normal desktop case
and it disagrees with existing practice for many years.

If I pull out my network cable while making some adjustments in my
rack, and then plug it back in, I don't expect to lose my static
routes on that interface.

That doesn't make any sense at all.
