I owned the Microsoft ASN1 library for a while around 2005. It was a maintenance nightmare and I spent a lot of time fixing static analysis derived issues. That said, I always found the standard quite interesting with different encodings based on the degree of prior shared info or format. My assumption is that not-invented-here is part of the why it’s not used.
