Sure, I agree. The problem here is that there are plenty of solutions always in the works and always discussed here, there and nowhere.
4 weeks is simple, clean and a first step. Once we make that first step we can start tweaking it further.
If we become stuck in discussion of 10% instant powerdowns with a burn, or a token redistribution, or a 2 week with 15% or a 5 week with 50%, or whatever, nothing will be done and we will be stuck in a perpetual discussion with no one taking a leap and actually doing something.
Lets do this and talk about everything else afterwards.
