Things do not always go the way kernel developers think they will. When the kernel gained support for the creation of read-only transparent huge pages for the page cache in 2019, the developer of that feature, Song Liu, added a Kconfig file entry promising that support for writable huge pages would arrive "in the next few release cycles". Over six years later, that promise is still present, but it will never be fulfilled. Instead, the read-only option will soon be removed, reflecting how the core of the memory-subsystem has changed underneath this particular feature.
