To summarize, “early” allocation has been done by the IS-IS Designated Experts. However, these allocations have been permanent as opposed to temporary. If there were ever a problem with an early allocation, the allocation would need to be deprecated rather than simply expire. Thanks, Acee

Are you now saying this has been invalid process for all of these years?? No, not exactly. What I’m saying is that the rfc7120 process doesn’t apply to registries which are Expert Review only; specifically, look at §3. For Expert Review only registries, IANA still has to be in the loop when doing the allocation, because they are the interface with the DEs. However, unlike early allocations done through rfc7120, the DE-assigned ones don’t expire…and the requirements for Expert Review may be simpler. So, the allocation may be done “early”, as in before the process is complete…which is perfectly fine, as long as there are no explicit instructions in the registry-creating RFC, and the DE approves. For example, a registry with an RFC Required policy needs an RFC — obviously! So the rfc7120 process allows for the early (= before an RFC is published) assignment. As part of the process, the assignments expire every year and have to be explicitly renewed….in case the work is abandoned and never completed, for example. OTOH, unless explicitly indicated in the RFC that defined the registry, a DE may assign a code point at pretty much any time (see §5/rfc8126). Again, IANA can correct me. Alvaro.
