Why do we need three variations? Do we actually have issues with input
binding where the discrimination matters? We never had any problems
before, when we just had a date/time object.

Creating a hard dependency on mxDateTime will place us right back into
the problem that we had with "dbi". People like simplicity and they'll
cut corners. I've been using mysqldb quite a bit lately, and it doesn't
use dbi. I doubt that it would change to use mxDateTime.

People want to distribute a single .c file and be done with it. That is
definitely easier on the module implementor than using mxDateTime.

I understand that you want to see people using your module, and I
generally agree with it, but I don't think it is a good idea for us to
mandate it. The API must support a DateTime(ticks) function which can
map onto a simple dbiDate-like object. A module implementor must be able
to use a simple ticks-based object (e.g. copy the code out of the
(deprecated) dbi module).
