Many people misunderstand how software is written in regulated industries, and assume that a standard is necessary. In practice, this is not the case. Note that Ferrocene[1] had to produce a specification[2] in order to qualify the compiler. But there isn't a requirement that it must be a standard in any way, only that it describes how the Ferrocene compiler works. Nor that it be accepted by upstream. 1: https://ferrous-systems.com/blog/officially-qualified-ferrocene/ https://ferrous-systems.com/blog/officially-qualified-ferroc... 2: https://github.com/ferrocene/specification https://github.com/ferrocene/specification
