Possibly the result of an industry scarred by the experience of depending on a TLS library that everyone thought was secure because “hey everyone is using it”. Now they want to make sure they understand and control critical security infrastructure.

Multiple implementations of a protocol are by no means a bad thing. The opposite is a problem - too few implementations means that the implementations dictate the spec and creating something compatible requires implementing bugs of those implementations too.

That said, I’d be surprised if we still had this many implementations 5 years from now. I think at least some of those will become unmaintained and instead use what Google/Microsoft/Mozilla/Cloudflare have developed.
