While I understand your frustration with recent chaos caused by poor 
planning, I have to respectfully reject your proposal for the following 

Firstly, implementing a 30-day minimum period between releases would 
punish users who have outdated tzdata solely because they are ruled by 
incompetent governments. While it may be easy to blame politicians for 
poor planning, citizens and businesses should not be penalized for 
factors beyond their control.

Secondly, deliberately making the latest tzinfo inaccurate would only 
lead to more issues rather than solve them. Accurate and up-to-date time 
zone information is essential for global communication and coordination, 
and any intentional inaccuracy would create confusion and further chaos.

Whatever information is solid before the release date makes it on the train.  Otherwise it can wait another 30 days (at least).
