I still recommend primer whenever you paint over epoxy, for two reasons:

1. It looks better. The primer fairs out your imperfect sanding job. (Your sanding job is perfect, you say? Wait'll you put glossy paint on.)

2. Primers seem to have a "crosslinking" effect with the epoxy. Primer simply sticks better to epoxy than glossy paint does, or at least that's been my experience. Last summer I polled some professional boatbuilders and they agreed with me, that they had better paint adhesion when primer was used as an intermediate step.

I get a lot of calls about primers for varnish; there are none.
