doctrine/cache will be abandoned doctrine/cache#396
psr/cache is the PSR6 interface
psr/simple-cache is the PSR16 interface
We should probably favour psr/simple-cache (which at first sight seems to be enough for our usecase) unless there are limitations which forces us to use psr/cache.
This is a breaking change. It notably impacts thecodingmachine/tdbm-bundle as this cache interface is used in the configuration.
