Ah, right, I forgot about CONFIG_NTFS_RW as I've never enabled it.

Judging from the now removed Kconfig entry perhaps not that many people
did:

	The only supported operation is overwriting existing files,
	without changing the file length.  No file or directory
	creation, deletion or renaming is possible. 

but I guess it still makes my argument above mostly moot.

At least if we disable write support in ntfs3 by default for now...
