I... wouldn't use it for a greenfield project either unless I got good at porting Luke Howard's Swift ASN.1 stack to whatever language I might be using that isn't C. For C I'd just use Heimdal's awesome ASN.1 compiler and be done. Even then I would be tempted to use flatbuffers instead, or else I'd have to go implement OER (a bunch of work I don't really care to do).

The problem with ASN.1 -- the only real problem with ASN.1, is lack of excellent tooling.
