You can probably just ignore them as a concern at this point. Nobody is going to want to use them in new products. They might keep going as a educational novelty but the magic is gone as far as using them in commercial/industrial products.
What makes you say that? Plenty of commercial operations would use them if they could purchase them at scale
Because you can't purchase them at scale. And haven't been able to for a year. If I'm making a product I'm not going to pick something I can't get. And I'm not going to switch back once I've found something else.
