So, how does a driver manage the aliases without a pool of available
addresses? I can't imagine another way right now.

In general, your above proposal sounds good to me. With my lack of
imagination regarding a different alias handling, I could also see that
i2c-atr already provides the alias to the attach callback. But if you
teach me another way of alias handling, then I could agree that your
proposal makes sense as is.

And yes, the "i2c-alias-pool" is definately optional.

Happy hacking,
