Putting this in a comment since I didn’t want to address it in the main body of the post:
The main reason this is unlikely to happen is election cycles. Governments have a short time period in which to make their mark, and if the impacts of all their policy changes are only felt towards the end of their mandate / beginning of next government then it’s going to be difficult for them to win reelection.
This is even worse because ministers/heads of department are often even shorter lived than governments, so they’re under high pressure to prove they’ve done something.
It’s also much easier for the next government along to roll back all the previous governments changes if they aren’t yet applicable nationwide. For that reason there’s a strong incentive to make all policy changes as sticky and hard to rollback as possible.
