Right, I read the function which provides the functionality, but my
point is; I don't think my patch changes the semantics in a way which
would adversely affect this option.  If you think that it does, can you
specify how please?

Does the sysfs method create a i2c_device_id table?  If not, how does
it probe successfully pre-patch?
