We actually support this feature:

commit df3687ffc6653e4d32168338b4dee20c164ed7c9
Author: Florent Fourcot <florent.fourcot@enst-bretagne.fr>

    ipv6: add the IPV6_FL_F_REFLECT flag to IPV6_FL_A_GET

Add that time I tried to stick to the common practices at that time and
was against any kind of global sysctl enabling a reflection mode for
flowlabels. State of art was to keep some uniqueness in flowlabels, thus
also the introduction of the flowlabel_consistency label.

We basically can support reflection nowadays globally pretty easy, as we
have soften these rules a lot.

Bye,
Hannes
