One problem we have with this setup: If two devices are on a port,

I assume you have considered fixing the route part by using fe80::1
(f.e.) as router address on all relevant VLANs?
In fact we use a consistent HSRPv2 config on all our subnets, so the
gateway *is* always the same; not fe80::1 but fe80::5:73ff:fea0:1. So
basically, yes we did this.
What reason spoke against it?
As above, none ;o)
You'll still have the "using wrong prefix to source packets" problem
though (which could be fixed using dhcpv6 if your equipment were inclined
to support it).
Sure. I guess I should re-check, now that we're on IOS 15SY; maybe they
finally fixed the bug - I did eventually get them to acknowledge that
looking up the DHCP server next-hop and getting an output interface of
Null0 and a source IP of fe80::... was a bug, not a feature request :o/
