There is an invalidate* functions on the cacheBackendInternface however I don't see a) it used, b) a usefulness to include this over their equivalent delete function. Is there ever a need to pull an expired cache?

May as well save the memory/database storage by deleting it over setting its expiration time and remove this api (or map it to delete*).

Ok. I see the get method on CacheBackendInterface takes an allow_invalid invalid argument (that no-one uses).

I was actually wrong, there are also two calls to invalidateAll() but they're unnecessary because we don't ever use them as invalid items, it just shows that the methods are confusing.

We discussed before if we should deprecate them and I think now that we shoud, so here's a patch.

Also confused about the \Drupal\Core\Menu\MenuTreeStorage::rebuild(), why would any cache entries ever not have the cache tags?

The last submitted patch, 7: deprecate-invalidate-2234835-7.patch, failed testing.

This should fix the unit test.

This patch looks sane so far, but I strongly believe we should add some @trigger_error statements at least onto the cache implementations in core as well as \Drupal\Core\Cache\Cache.
