Why?

You should be able to do that today if you're so inclined, but, you lose
some features.

If they're routing a /64 to your gateway, you're all set. If they're not,
then, how are you getting the /64 in the first place?

None of the providers I've talked to are using single /64s for any
other reason that CPE limitations. The worst case I'm aware of
today is Free.FR who is limiting their customers to a /64 today
due to CPE problems, but, has allocated /60 per customer and
plans to make /60s available as soon as the CPE can support
it.
