People can put things on the Internet without asking permission.  That's one of its fundamental tenets. A large company may wish to experiment with an NTP extension (e.g., QUIC checksum complement?) and only has to be concerned that their experiment will not conflict with other people's experiments, or standard extensions. Perhaps you don’t know that this happens very often with HTTP and email, often via "X-" headers (as Ulrich said). It also happens with DNS (new RR types), and TLS (new crypto algorithms among others). It is common practice for protocol registries to have a "playground" area.

In the larger IETF we have a great deal of experience in experiments concluding, being taken down, and official standard numbers being used. It doesn't happen overnight, but it doesn't take decades either.
