Sounds good

Not sure about that. If comments are just user text, then probably not.
I'm guessing you might want that for something else?
I would prefer it if you had a plan to introduce user definable
parameters, similar to custom_variable_classes. Perhaps call this
"custom_table_options". So when we load a table and it has an option we
don't recognise we ignore it if it is one of the customer_table_options.
custom_table_options will help us define special behaviours for
datatypes, indexes, replication etc that relate to the specific role and
purpose of individual tables.
