As far as I know, every OCXO and most everything else has its own
internal supply and further regulation of some sort, running from the
crude real world sources applied. As long as the supply you give it
meets the specs and other characteristics, stated, it should be just
fine. Making the outside supply part better may or may not make the
thing work better, but maybe it's worth a shot.

Relating to power supply filter capacitance multipliers from the
concurrent 1/f noise discussion, are you talking about this kind of deal
maybe?
