De-facto standards are as good as people implementing them, however in order to enforce non ambiguous implementations, it has to be de-jure (e.g. a standard track RFC). While I’m sympathetic to the idea, I’m quite skeptical about its viability. A well written BCP would be much more valuable, and

BCP38 is an RFC, 2827. It is a grand advise if you can: -find someone who is actually well versed -afford that someone. Personally - when in early 2000s I had to write complete community tagging design for a multi country network, I wish I had a “how to” Regards, Jeff > On Sep 9, 2020, at 15:
