Both of these goals can be reached without the fee switch by just utilizing the treasury.
- Incentivizing LP migration can be achieved by a liquidity mining program
- “making a statement” about Uni token can be achieved by having governance rewards from the treasury.
If participation in Uniswap governance is rewarded through staking rewards to governance participants, more voting power becomes available in case there is an important decision to be made.
It doesn’t mean that these rewards have to come through fees, though.
They can come in the form of inflation (treasury rewards distribution) towards actors who presumably bring more value to the governance token.
I’m yet to find a good reason why making Uniswap V2 a worse product for LPs and traders is superior to distributing the treasury that is meant to be distributed.
If the treasury is not distributed at a decent enough pace, Uniswap governance becomes more centralized to investors and the team due to the vesting schedule.
