> Although probably not the actual intended effect

This is actually a really common intention in laws like this. Get the tax cuts during your term, and then kick the can down the road so your successor's term is marred by the bad law. If your successor wants to fix it, they need to pass a different tax to recoup the costs, and incur the publicity of "raising taxes".

This is 100% the intended effect of leaving a bomb like this unaddressed then stalling all legislation halfway through your opponent’s term. You make them look incompetent and then you complain about how they never fix anything, even though they never get anything done because you’ve stopped cooperating. And even though you’ve stopped you can keep complaining about how they always include things you don’t like in legislation so that’s why you never cooperate. The solution is simple in your eyes: just do exactly what you want and only what you want and then you’ll cooperate. This is how a lot of a certain party was talking on the news from 2021 to 2025 when they were interviewed.
