I am working on the migration of a dedicated cache implementation module from D7 to D8/9 and I haven’t found yet use cases for $allow_invalid=TRUE when we fetch a value from the caches (when an entry has been deleted, it seems logical to receive a FALSE as answer). And as this parameter is in the API, I suppose that it is used, but when?
If someone could give me some information about the use cases for $allow_invalid=TRUE, it would be really helpful in order to finish this migration :)

I am developing an intranet for my company, in which data from trucks, customers, trips, drivers, etc. will be managed.
I want to develop this intranet in Drupal 8. I have a lot of experience in Drupal 7, but not in Drupal 8. I will do everything programmed, I will not use Drupal nodes.
I have read about the folder structure of a module in D8. I have read about the structure of a module's folders, but I have some basic doubts about how to structure the custom classes that I will create.
