I've seen this last point come up a few times, and I really don't get it.
If you're multihomed with multiple PA GUAs, yes, you'd want each RA to track its corresponding WAN availability so your devices are using a prefix that has connectivity.
If you're a single-homed leaf network, why on earth wouldn't you want to generate RAs for your statically-assigned prefix all the time, regardless of the state of your WAN connection?
