I'd be against this.  It would result in more use of unofficial and unreleased data, or manual hacking of downstream systems.

A better plan is to work on two fronts: 1) Increase awareness so that governments might try to provide more lead time in the future, and 2) work on technical solutions to improve distribution of tz data, reducing the amount of lead time necessary (which varies per implementation).

Just an onlooker... but if you changed the policy to an automatic 90 or 180 delay between notice of tz change and public release of new databases versions... that would tend to draw public attention to violations of the policy.

"it's" should be "its".)
