Yes it requires the pool operator to enable it, but I don't think that means it should be discarded as not useful. Rather, a push to make every major pool operator run it (and specifically to enable the job negotiation protocol) would help to protect against censorship of individual transactions. It might also have some legal benefits for mining pools. If it were to become the default, and some government demands that a mining pool censors some specific UTXOs, then the mining pool can point to the fact that they do not have the power to do this and the miners themselves can choose to include those UTXOs if they choose.

There are also a number of other upgrades that might entice pools to start using this software: https://braiins.com/stratum-v2
