The main thing I am concerned about is that if we pick the approach I've
implemented, then changing our minds to a format-based approach will be
harder.  I think that's the case because the user-facing "set"s would be
hard to migrate to a format-based approach.

And, FWIW, I think the format-based approach isn't super hard to
implement.  The main problems there are design problems: whether to
remap the names of tables and fields; how to handle the trouble cases I
found in my initial investigation; and of course whether there are more
difficult cases lurking.

Overall I think I'm in favor of the approach I've posted, but I think
it's a good to examine this idea critically.
