Would it be possible to add an I2C switch, and an easy way to use it to “wrap” I2C components? Something like this:

I think it will be impossible / very hard to meet any serious power requirements without this, so would be great to have 🙂 .

Qwiic is I2C, just using a specific connector and 3.3v levels. That switch can be used on any 3.3v I2C system

Yes, what I mean that it would be great to have a “wrapper” (or “intermediate I2C switch”) to be able to fully switch on and off stuff on a la carte designs.
