It's true that this profile mitigates the amount of information that can be

But in IPv6 we have other configuration methods - such as SLAAC - that

than stateless DHCPv6.
This document should recognize that at least on IPv6-only networks, it is an
option
not to use DHCP at all, and that option has substantial privacy benefits that
are in
many cases above what this profile can provide.
Well, section 4 of draft-ietf-dhc-anonymity-profile-07 says:
The choice between the stateful and stateless scenarios depends on
flag and prefix options published by the "Router Advertisement"
messages of local routers, as specified in [RFC4861]. When these
options enable stateless address configuration hosts using the
anonymity profile SHOULD choose it over stateful address
configuration, because stateless configuration requires fewer
information disclosures than stateful configuration.
That seems pretty close from what you want, at least as far as "stateful
DHCPv6" is concerned.
