Review comment:
       What do you think about moving this to the base class? Then we wouldn't 
need to add the "no refresh" method to get metadata and could access `current` 
directly. This PR also makes it far less likely that implementations will 
override `io`, since a new one can be plugged in easily through table 
properties.
