> If there can't be any common sense exceptions to the 90-day policy, that's just bureaucracy by itself.
Its worth noting, as pointed out upthread, that the only reason it was released in January at all was because when Microsoft asked if their planned February release was going to cause a problem with the 90-day deadline, Google informed them the the 90-day deadline for that bug was 11 January and that that's when disclosure would occur. Clearly, the fixed deadline already achieved part of what it was intended to -- encouraging vendors to fix security issues more quickly.
And I'm not sure that there even exists such a thing as a "common sense exception" to that policy, but extending it simply to accommodate a vendor schedule that delays releases of security fixes to predetermined dates isn't such a common sense exception even if any exist. Its simply favoring the bureaucracy of fixed patch schedules over the purpose of the disclosure policy, which is encouraging vendors to more timely release fixes for security bugs.
