I've discussed that one before in ENOG. I've heard a concern that an
ISP is not really going to figure out the usage of leased IP
addresses, and if at some point the backup address in VRRP would start
to be used separately for its own purposes, the ISP would miss that.
So, like I said, there's apparently no real reason to be so specific
about those borderlines.

The issue with common sense is that common sense just doesn't scale.
I've heard about 5 different opinions on this one already in ENOG. All
those five are based on what the respective backers believe to be
their common sense.
