I empathize with your position, but I think your last sentence defines a very large market. If I look at it from a product lens, Supersonic is optimizing performance, UX and tooling within the hybrid space, which is valuable offer.

From an engineering perspective, I would inspect the native API bindings and look for / test optimized rewrites of the Cordova runtime. I believe they are getting close to 3x gains over the stock Cordova runtime.
