Talks again arose about fee switch activation with the launch of Uniswap V3. GFX Labs, maker of the Oku, a front end interface for Uniswap, proposed a plan that would test out the protocol fee distribution on a few pools on Uniswap V2 that received a lot of attention. But talks ultimately fizzled out, due in part to concerns that activation might drive LPs and liquidity away from the platform, as well as legal fears.
