I love what they are trying to do with Stratum V2 but as far as i understand it has a similar problem as taproot. There is no strong incentive for individual actors to adopt it but if they did it would be better for the network as a whole

actually there are some really good reasons for miners to adopt it:
  • better security (that is to say any security) between individual miners and their pool operator to prevent people from stealing their shares
  • way less networking overhead between miners and the pool
  • miners can propose block templates!
