Yeah. Quite aside from the code bloat and grammar bloat, my main
fear about that would be the assumption that we could wedge a consistent
syntax for this into all those different sorts of CREATE commands.
At the very least we'd probably find ourselves having to make those
keywords more reserved than they are now.
