So far I haven’t heard any good reason. TLS issues are not more common than other components, at least in Go. Maybe people are just a little traumatized by how often other TLS stacks broke in the past?
We maintain two Go versions with very conservative patch releases specifically to allow quick deployment of critical and security fixes. If that still doesn’t allow for quick patching of security vulnerabilities, it sounds like a process issue (on our side or on the application side), not a reason to make TLS special.
