User Story

As a liquidity contributor, I think

• non-zero withdrawal fee rates is a barrier for funds to enter the liquidity pools, and,
• lack of ability to update fee rates is another obstacle for the liquidity pools to adapt effectively to the market.

To improve market freedom and liquidity, I think it is better to allow updating of liquidity pool fee rates. Therefore, I propose the following new rules:

• The withdrawal fee percentage of a liquidity pool can be updated by the owner, but only to zero.
• The taker fee percentage of a liquidity pool can be updated at any time by the owner if the withdrawal fee percentage is zero.
