IPv6 next-hops can be distributed in OSPF and BGP in mikrotik as well, but it's maybe not 100% ready for prime time.

Streaming services essentially all support IPv6 so that's a big win. As is gaming services. Maybe general web browsing and other odd apps have some teething to do still but I think we're pretty much ready for dual stack right now.

Note that it's possible to route IPv4 traffic over an IPv6-only backhaul
(at least with Linux gear):

# ip r add 10.0.0.1 via inet6 fe80::1 dev wg0
# ip r | grep 10.0.0.1
10.0.0.1 via inet6 fe80::1 dev wg0

There's an (expired, unfortunately; we should fix that) IETF draft
describing the general mechanism:
https://www.ietf.org/archive/id/draft-chroboczek-int-v4-via-v6-01.html

And an extension for the Babel routing protocol to implement this (so
you can route v4 traffic through a whole network without assigning
anything other than v6 link-local addresses to the intermediate nodes):
