I wasn't the one who closed it, but here's my perspective on the matter of that question:
It is very, very difficult to answer a question of the form "what standards should be enforced" constructively. It pulls too much from the domain of what is essentially pure opinion and "opinion, by itself, is noise." It's like saying "at what point should a brand new rapier fighter start competing?"
Well, that depends on the school, the tournaments, and the goals of both the individual rapier fighter and the school. It's hard to say, a priori, what would even constitute a "good" answer beyond "what are the standardized rules that you can find on the website" because you haven't identified why the official rules are in any way inadequate.
You see this in Berin Loritsch's Answer, which is a reasonable attempt at covering the factual basis, when he says:
I personally don't think that there is any way to come up with an authoritative or even useful list of techniques that are absolutely required. If you take a dozen sensei, you will have a dozen answers. Even on the commonalities, there will be disagreement on the emphasis necessary.
This goes to the heart of the matter: If you can't even standardize to the degree of "who best represents the school" or some other criteria, then there pretty much cannot be (from the nature of the question) a reasonable subjective answer. Especially since there are no real predicates there, just a general question of "what should be the criteria?" This is made more complicated by that you seem to be inquiring for general interest, rather than providing specifics of the situation that you are trying to address (this isn't always necessary, but it does help to provide context).
This isn't to say that something can't be made from the core of that question by narrowing the scope, modifying the wording, or providing additional context but it isn't obvious on the surface how an outsider could transform it.
For example, consider the following:
"I feel that my students are being hurt by competing too early because they get caught up in winning or losing the tournament rather than on improving at the art itself. I believe that the competitions are still valuable, but don't want to throw them in until I know that they are ready. What would be some good things to look for to know when they are ready?"
It would be fair for people to want additional details and it is a challenging question to answer well, but I also don't think it would get immediately closed. On the other hand, I can't exactly edit your question into that since it may not be what you are actually asking.
