Indeed, and it also is a transition mechanism for the very same reasons
that 6to4 is.

Even if there are different use cases indeed (as you explained it very
well yourself)

you can't deny that 6rd is 6to4-bis.

Oh, yes indeed, on can!
(Depending, of course on what you mean with 6to4-bis, but no one can be sure 
what you mean).

- 6to4 delivers native IPv6 prefixes to customer sites, which 6to4 doesn't.
- 6to4 has known operational problems, not 6rd.

The difference is in
who configures/manages it,

not how it works;

See above.

the 6rd code base is a
superset of the 6to4.

Although it has been convenient to deploy 6rd starting with existing 6to4 code, 
one can write 6rd code that doesn't work for 6to4.

The difference is more a matter of network design
than core protocol.

It is a matter of clean IPv6 service, transparent to users, vs service for 
experts who know what they are doing.
