I agree we should go past the typical M/O debate, learn from it.

One way I read the ongoing discussion, if I am not wrong, is that there
is difficulty created by the lack of a flag specific to IA_PD ("As far
as I know the M flag is linked only to IA_NA. As far as I can see IA_PD
is not linked to the M flag at all.").

Am I the only to read this as maybe a hint towards necessity of creation
of a new flag akin to M/O but specific to IA_PD? I.e. it would be allow
a Router to see whether it may be able to specifically request a
Delegated Prefix even when it would self-configure its address by other
means than DHCP.

(in the past some local thought was given about how RA would advertise a
capability of delegating prefixes, e.g. this 'D' flag in a draft:

>     0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
