It was an effort to enhance fscache as a kernel cache for lazy pulling (at least according to previous Incremental FS discussion [1]) and EROFS over fscache was the in-tree user of this mode. fscache has since evolved to be netfslib-oriented, serving network filesystem inodes via the netfs library, but EROFS never acts as a network filesystem and we need to cache golden filesystem images rather than individual EROFS inodes. Since EROFS over fscache is now removed, clean up netfs/fscache/ cachefiles upstream too.
