But to meaningfully support a thing - per the original author - "compiles on a version of the ISA" (and there are many of those for ARM) - and "actually works as intended" do have to care about things like "this ARM core runs these extensions. This ARM core is really just a coprocessor to a binary blob processor. This ARM core is buggy as fuck but no longer supported by the vendor" matter. Where's your source of randomness for crypto, just as a starting point?

People want - to borrow from the BSD world - FreeBSD levels of support for specific chipsets and features, with OpenBSD levels of support for security, and NetBSD levels of portability. These are not compatible outcomes, and folks should stop pretending that they are.
