We worked towards BRs-compliance as quickly as we could, anticipating
that the BRs would eventually be "adopted and enforced" by at least one
of the browsers.

Well, I tried to apply logic. That left me concluding that the only way
to square "Effective Date" with "not mandatory...until...adopted and
enforced" was to interpret "Effective Date" as the date on which using
(for some definition of "using") the BRs became optional (instead of

TBH, my recollection is that it wasn't really that clear back in July
2012. I think we all anticipated that the browsers would eventually
adopt (future tense!) and enforce the BRs, but it was only when Mozilla
updated their CA Policy in early 2013 that the BRs were actually
"adopted and enforced" (past tense!) by anyone.
Mozilla asked CAs about BRs-compliancy back in January 2013 (some 6
months after the "Effective Date"). It's clear from the responses 
that some CAs were still working towards compliance.
We share Steve Roylance's opinion that, unless they are required to
address flagrant violations of expected behaviour, policy changes should
be forward looking.
For our part we would be content to see the policy changes applied from
the date they are announced, but making them retrospective back to 1st
July 2012 when the evidence shows that that date was not universally
complied with seems to have an uncertain impact.
