You actually imagine wrong in most cases. Many do, but, not most.
Most use mDNS for such things these days, actually.

I would agree. I think that customers that WANT privacy at the expense of having their prefix
change often being able to request such service might be a good value-add service you could
offer, but, I think the vast majority of customers would prefer prefix stability.
I think that the privacy implications of a stable prefix are vastly over-stated in this thread.
