We can't compel people to continue supporting it any more than we can

"killing" 6to4. We don't have that kind of power.
But you can give them a big excuse not to support it.
Customer: "Where did the 6to4 support go?"
Vendor: "The IETF declared it historic so we removed it."
Vendor: "I repeat the IETF declared it historic."
6to4 on by default is wrong.
Making 6to4 historic is a knee jerk reaction to a bad default setting.
Fix the default. Don't make 6to4 historic.
I fully agree about your description of the purpose of "historic"
for vendor and its usage by vendors.
The only sensible use of historic is to promote active de-support
on the part of vendors -- literally for "ripping things out".
I just did that myself 4 weeks ago, justifying the complete removal
of support for MD2-based digital signatures from our PKI software
with a pointer to
http://tools.ietf.org/html/rfc6149 "MD2 to Historic Status"
Moving 6to4 seems premature by several years.
