This should provide a direct answer to you question of "why"?  But I
suspect the underlying question is why divert sockets aren't supported
for IPv6.  I don't know why.
because no=one has done it and because divert sockaddrs are ipv4 sockaddrs

you would have to make a new divert6 protocol.
That's not impossible, but no-one has done it.

I've been looking at it, with hints from rwatson@ and bms@, but the
problem right now lays in the way you can do dynamic protocol
registrations with IPv4 but not yet with IPv6. Every time when I
get one step further I end up with a new problem :-(

Let's call it a learning excercise!

you could implement a whole new protocol family of which there
was a single protocol..  divert.
    so you would open a socket of type.

     sock = socket(PF_DIVERT, SOCK_RAW, DIVPROTO_6);
instead of

        sin = socket(PF_INET6, SOCK_RAW, IPPROTO_DIVERT);
