I will suggest you hang onto the old part once removed.
As best I can tell, the only thing that goes wrong with them is they get plugged up with (potentially gummy/sticky) dust, which means there is hope to potentially restore them with a careful disassembly and cleaning. There are parts inside smaller than the tip of a pen, though, so it requires some care.
If they truly are unobtainium (as is seeming to be the case), we will need to find a viable strategy to refurb the old ones.

Every single one I've replaced has died due to the bimetal spring breaking.

Ah...that's a more difficult item to replace.
The several I've gone through have been mechanically intact, but have a slight vacuum leak (not external - the intended vacuum path, just letting too much through) which screws with their accuracy, causing them to prevent the heat staying hot. The best I can come up with for why they do that is dust plugging them up.
I took one apart just to see how it worked. Not much to it but a needle moving in an orifice and the spring. If the spring isn't broken, best I can guess is the needle jams and hangs open. Possible that flushing it with some gentle solvent would un-jam it. I really don't know, and I don't have a bad but intact one to test. Once you take them apart completely its pretty much impossible to re-assemble. You have to bend the tang on the spring and then there is some tension adjustment that I don't know how to duplicate.
