The urgency is quite irrelevant. In many locales you will still have to ask voters for permission and/or have a constitutional referendum in addition to having the local legislature acquiesce. All of those parties can do whatever they want and a large percentage of them don't understand and DGAF. This dynamic plays out over and over for countless issues, this is no different.

In the meantime, tax authorities will require compliance as the law demands without any regard for another tax authority requiring something different.

I'd be perfectly happy for pennies to disappear but I am not ignorant of the realpolitik that makes implementation nearly impossible. Wishful thinking won't make it so.
