can anyone confirm when we deprecated keystonev2? i see a bp related
to deprecation that was 'implemented' in 2013.
i realise switching to v3 breaks many gates but it'd be good to at some
point say it's not 'keystonev3 breaking the gate' but rather 'projectx
is breaking the gate because they are using keystonev2 which was
deprecated 4 cycles ago'. given the deprecation period allowed already,
can we say "here's some help, fix/merge this by
<date_before_end_of_newton>, or your gate will be broken until then"?
(assuming all the above items by Raildo doesn't fix everything).
