Yep Arjan the

already polluted their gene pool anda whole load more, to be honest the only places you are likely to find unpolluted genetics still growing natively today are those that have been at war/no travel zones since the late 80's early 90's.
Really pleasing to see that the people currently visiting the remaining areas aren't trading their crappy indoor
Hybrids but rather giving them proceeds or bringing them alternative non-invasive food species/buying them fruit and veg seeds locally that they can't afford. Thus givingthem opportunities to diversify too. I really hope they don't duck it up.
