I'm not worried with this, because I grew up acquiring the taste of highly diversified bananas. Honestly, the cavendish bananas sold in the US grocery stores is not my best tasting banana if there were more choices. For now the cavendishes are the cheapest among the occasional other varieties appearing in specialty stores, but I can guarantee you that the cavendishes are not very versatile nor the best tasting, but the problem is how soon can you adjust your taste to like other types of bananas? If people can't change, then it is indeed a race with time in finding a suitable substitute for cavendish banana.
Currently I grow about 10 types of cold hardy bananas in my yard, in USDA Zone 9, Northern California. I have two bananas blooming at the moment.
Here's my album. Haven't posted the pics of my blooming bananas yet.
