Why would it be sold as a species?!
Because they grow much faster than the parents, and are easier to sow. jackii in flask or malipoense in flask have a quite low yield in most labs. The hybrid really germinate like a weed.
The F2 are expected to have malipoense or jackii leaves, cannot tell them apart by the leaves, and maybe later by the flowers, from the real species. Same for primulinum, a hard to grow very rare species whose most plants in the trade are in fact Pinocchio siblings (including Indonesia, where many plants have been imported as a part of a trade against others species of paphs), liemianum, glaucophyllum, tranlienianum "red form", some coccineum from seed. The hybrids nearly always grow faster and make "nicer" plants for the consumer.
Apart from that, the flower is maybe cute to some, but a very good jackii or a very good malipoense will surpass any plant from that hybrid. The clear purpose of such breeding is to get fast growing plants, nothing else (well maybe later "fast growing species").
