I would like to propose one more output format, optimized for

The packed array is a piddle like interface, which is 0 overhead -
no conversion or copying is made, the driver simply implements an
IType over the native data that it can provide.

Result matrices are given back in the natural buffer size of the
driver, or a user defined setting.

I also think that your compatibility concerns shouldn't matter - we
already have DBI for perl 5. It provides all the compatibility we
need. I'd like a more accessible binding interface, and more
flexible placeholders (especially for safety). Since Perl 6 has more
explicit types I'd like DBI to be able to leverage these, too.
