I was thinking that if the maintainers were planning on porting some other larger part of the codebase, then starting with something small/relatively inconsequential would be a good first step, and keeping it in C wouldn't provide much benefit once said other larger part were ported. > Also, the package wbond/asn1crypto has shown that doing ASN.1 in pure Python can be quite fast. Interesting! I'm curious why the maintainers didn't opt for that approach instead. > The ability to try the feature out and still have a plan B if it doesn't work out Would people have tried this feature out if it were made opt-in? It's clear that the initial announcements reached far fewer people than one might like, and I honestly have no idea how many people would see a build-time warning.
