No, I do not agree.

The sql backend is part of the MTA; features added by offering a sql
backend for tables of this sort (I'd use a cidr access restriction
in postfix) are still features of the MTA.

And actually using the power of sql when using sql is not a trick;
rather it is the /point/.

IOW, the MTA is the sum of its parts; when using sql lookups the db
is part of the MTA.
