#918538: Decouple cache tags from cache bins → makes Cache::invalidateTags() a simple wrapper for \Drupal::service('cache_tags.invalidator')->invalidateTags($tags);
As a follow-up, we could look into injecting this into services instead of calling out to the static method. That should allow us to simplify unit tests that currently need to set up a container.
Inject into new services and existing standalone services that are not commonly subclassed. (E.g., changing default plugin manager would be a bad idea at this point).

It's likely this issue predates Contrib.social: some issue and comment data are missing.
The discussion in #31-34 still stands, the entity handlers can't use dependency injection still.
However, there is no real reason for Cache::invalidateTags() to exist as a wrapper - the static method predates the \Drupal class iirc. We could deprecate that and use \Drupal::service('cache_tags.invalidator')->invalidateTags($tags); in those places, and use injection everywhere else.
