Have you personally inspected every flytrap that's growing in the wild to ensure that it doesn't have these odd sorts of traps?
Trictherfalle isn't really a "genetically weak" flytrap like you all are suggesting. It grows quite vigorously and with normal traps that are very good at catching bugs for most of the growing season. It usually only gets these weird traps in the fall.
And the argument about "weakening the gene pool" doesn't make much sense. It's not even known whether the trait to make the odd-looking traps is dominant or recessive. And assuming it is dominant, most growers don't live in an area where their plants will be cross pollinated with any wild-growing plants and I can't see any reason to fret about this plant's genes being part of a seed mix in cultivation. But I think all of that is irrelevant anyway because even if Trichterfalle were to be introduced into the wild, it wouldn't pose a threat because it's a vigorous growing flytrap that would likely do well in the wild and add genetic variability to the wild population of flytraps. And genetic variability is very important in nature in order to provide species with the ability to adapt and evolve.
