No, no, no. We did that 10 years ago, killed all the code 3 years ago [1], let's not do the same mistake again, please. We have a sysfs interface for instantiating clients dynamically from user-space, it's way more powerful and flexible than your proposal. Just try plugging two different i2c-tiny-usb adapters on the same system and see the new code instantiate the wrong devices...
