Our preference system is designed around CIDR and the most specific prefix will win a lookup meaning a /32 settings are preferred over that of a /24.
A corporate network can have a policy changing that (aka, you are fired), but an ISP can't. The policies of IT departments and ISPs are not remotely comparable. This is a deliberate design choice.
As usual, ymmv. -david
