28606	Deprecate CachedStaticFilesStorage	Ed Morley	nobody	"`CachedStaticFilesStorage` has a number of drawbacks, and the docs in fact already steer people away from using it:
https://docs.djangoproject.com/en/1.11/ref/contrib/staticfiles/#django.contrib.staticfiles.storage.CachedStaticFilesStorage

An additional problem is that `HashedFilesMixin` has had to make several compromises in order to support `CachedStaticFilesStorage` which unfortunately also impacts users of the recommended `ManifestStaticFilesStorage` backend (see #28604). When these compromises were added in #24452, it was suggested that `CachedStaticFilesStorage` should just be deprecated/removed instead.

It's now too late to mark it as deprecated for Django 2.0, but we can do so for Django 2.1 which would end up with its removal being in Django 3.0 all the same anyway.

I started this mailing list thread about the deprecation:
