Why I was proposing the two staking pools is to cater to both short term and longer term investors.
Shorter term investors have more liquidity while still can participate in PoB and longer term investors who are willing to give up liquidity to show commitment by locking up have more power in governance.
The silly thing about the current system imo is that 13 weeks is such a tall commitment especially on crypto space to participate in PoB, one of our "unique feature". On the other hand, people with minimal commitment voting on the future of the chain looks like recipe for disaster.
If it's deemed to be too complicated to implement I suppose it's not worth it after all.

Custom duration lockup period that works with SP would be cool but It will never be implemented because it will never be on top priority lol.

If this proposal passes as is I am actually more in favor for 1 week instead chickening on 4 weeks, maybe I am too paranoid about exchanges voting. As for security... I guess we need to be more careful with our keys.
