Hi from 2023, @dcposch and I have a new proposal might be related to / could depend on this issue:
The basic idea is to allow to-be-precompiles to first have a tradition deployment and then if they gain adoption, the adoption can be used to justify a hardfork to include them as precompile, and such precompil-ify will be backward compatible and all existing using-contract will only experience lower gas on wards.
Our idea demonstrates one usage for the proposal of OP. In fact, if OP doesn’t get supported anytime soon, the incremental way is to treat Nick’s Deployer as the de facto “Precompile” of CREATE2
