You're kind of describing home assistant. It integrates with all the various non interoperable standards and gives them the same interface. (In the ui sense, but also in the sense that you can write scripts that cross manufacturer boundaries.)

I know, but I'd prefer if it came that way from manufacturer instead of hacking at it away.

Like, I converted one of (sadly out of production) mpower pro power strips (it was great, cheap 6 socket with power measurement per socket) to talk to it but it wasn't exactly great experience.

The config of IoT devices should be just "start an app, point it to your (or cloud) controller, done", not "browse compatibility list and hope HASS supports it and the manufacturer won't break that support on update".
