I've just ran into a problem where I am loading entities for which the languages are not anymore activated in the system. When I call getTranslationLanguages() then only the subset of translation languages is returned, for which the language is activated in the system.
I would say that it is our problem if we run into such a situation, however there is this interesting code in \Drupal\Core\Entity\ContentEntityBase::getLanguages():
// If the entity references a language that is not or no longer available,
// we return a mock language object to avoid disrupting the consuming
// code.
if (!isset($this->languages[$this->defaultLangcode])) {
$this->languages[$this->defaultLangcode] = new Language(['id' => $this->defaultLangcode]);
}
I think that in order to be consistent we should not differentiate between a language being default or non-default when deciding whether to return a mock object or not for it if it does not exist.
Return mock language objects for non-existing translation languages already present on the entity.
Needs work

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Seems the point in #11 needs to be implemented.
Also will need test coverage
Please read the comments too. #11 was not addressed. Not ready for review
