PSR-6 incompatibility about scrapbook

[matthiasmullie]

Actually, this behaviour is completely compatible with PSR-6.

PSR-6 libraries don't need to provide interoperability between different pool & item objects. A pool should only be able to store the item object that it created itself, not one that was created from another pool (from another library)

This was a heated topic for that PSR. The reason there should not and can't be interoperability between pool & cache objects from other libraries is that there is no standard way to pass the expiration time from an item to a pool. There is no default public method for that, so every library has their own implementation to pass that bit of data along.

In addition, Scrapbook does a bunch of optimizations (e.g. pool won't actually request the data from the cache when the item is created, but when it's actually used - batch-loading all the other in-flight values at the same time) that most (all?) other libraries don't, further making it impossible to provide compatibility...
