Those who are serious about killie-keeping will buy only from reliable sources and trust the sellers' reputation and integrity to maintain proper population codes. How 'pure' the line remains depend largely, again, on the integrity of the breeders, their effort, time and dedication.

Farm-bred killies are usually tagged 'Aquarium strain' since population details are either unknown, withheld or deemed unnecessary. No comments with regards to how 'pure strain' these are.

Said 'purity' is very hard to maintain, passing between hands and between raising successive spawns. However, it is made possible by maintaining dedicated tanks and culling all questionable off-springs.
With regards to burden of proof, one is never obligated to buy when in doubt. Buy if you trust or like. Don't buy on the slightest hint of misrepresentation. Do research proper.

If cross-breeding occurs due to flooding of habitats, etc, and if Mother Nature allowed the off-springs to survive, I'm not going to argue with Her.

I used to be anal with regards to population codes but preaching to the choir is a consuming task.
For some, maintaining the gene pool from which the killies are collected (and presuming that their natural habitat hasn't been destroyed by redevelopment), there remains a hope of repopulating that said habitat one day.
Personally, I now have neither the strength, stamina and time to care whether others cared or not. I keep, breed, raise what I like and maintain their lineage as best as my resources allow (and I've been poorer for that). Others can get theirs on Aquabid, Ebay and wherenot.
I encourage aquarium strains to newcomers on the learning curve but I'll scoff at the thought of intentional hybridization. If a line of aquarium-strain killies (for example Aphyosemion australe), appeals to you, then go for it. Maintain the line for a few years and then look back to see if it was time well spent.
Apologies if my response is blunt but I should be asleep, not posting.
I'm back & keeping 'em fingers wet,
