In #2204697-41: Move getConfigPrefix() to ConfigEntityTypeInterface outline several ways the the config_prefix and ConfigEntityTypeInterface::getConfigPrefix() documentation could be improved:

  1. +++ b/core/lib/Drupal/Core/Config/ConfigManager.php

    +      return ($entity_type instanceof ConfigEntityTypeInterface && $config_prefix = $entity_type->getConfigPrefix()) && strpos($name, $config_prefix . '.') === 0;
         return key($entities);

    Hmm. So if the entity type is an instance of ConfigEntityTypeInterface, but getConfigPrefix() returns something that is false, or the name doesn't begin with the config prefix expected... then what happens?

    This isn't introduced by this patch, but it seems like now this is a set of things that would mean the entity type were malformed if the first were true but not one of the others. I think. Can we get a followup to at least add an inline comment to document this, and maybe investigate whether this line is something that should be refactored?

    So the first and third hunks of documentation are added by this patch, and the first is what we have in HEAD. That means we're explaining what a config prefix is composed of in why in different ways in three different places. We should consolidate that and clarify it.

So re point 1. It is impossible for getConfigEntityPrefix() to return false with the current code. I guess what we need to do here is remove the FALSE possibility from the @return documentation. Also the if the name is not a configuration entity then ConfigManager::getEntityTypeIdByName() returns NULL so it is behaving exactly as documented.

Tried to consolidate documentation onto the interface and remove sentences which are no longer true. For example, config entity prefixes now are just part of what causes optional configuration to be installed - but the bigger picture there is that this is all about dependencies - if an optional configurations dependencies are met then it will be installed.

This looks good to me. Since alexpott created the patch, I went ahead and committed it (he can't).
