They're not forbidden, but I don't think they are useful. There's no
reason I can see why they wouldn't work, but I haven't actually tested.

They're allowed. RFC 6126 4.4.8 says
AE The encoding of the Address field. This SHOULD be 1 or 3
and MUST NOT be 0.
This means that the next-hop SHOULD be either IPv4 or link-local IPv6, but
may also be a global IPv6 address. I don't think I've ever tested babeld
with global IPv6 next-hops, but if it doesn't work, it's a bug.
