There seems to be a BC break in Symfony 3.4 when clearing/warming the cache.
Until a couple of days ago, it was possible to write to %kernel.cache_dir% during cache warming and the contents would persist. Now they are deleted when the cache directory is moved from de_ to dev. However, when using the $cacheDir parameter provided to the warmUp method, the files are kept.
I realize that using the path provided to warmUp is preferred, but we have different places in our code base where the path is injected to cache warming services through the service configuration. This way, we can configure a common path for shared cache objects and use a common cache service.
Example:

I agree that this could be solved differently. However, this change breaks the previous behaviour which has been there since several years.
