 read-only hierarchy and ``~/tmp/`` as a read-write hierarchy, compared to
 ``~/`` as a read-only hierarchy and ``~/tmp/`` as a read-write hierarchy.
 Following this good practice leads to self-sufficient hierarchies that do not

 relevant when we want to allow linking or renaming.  Indeed, having consistent

 rights to the minimal set of data.  This also helps avoid sinkhole directories,

- * This disambiguation has rather positive consequences.  Mounting a subvolume

- * will become ro.
- *
- * So, if the superblock creation request comes from the new mount API the

- *
- *      fsconfig(FSCONFIG_SET_FLAG, "ro")
- *      fsmount/mount_setattr(MOUNT_ATTR_RDONLY)

- * superblock ro and we shouldn't just undo it like we did for the old mount
- * API. In any case, it lets us avoid the hack in the new mount API.
- *
- * Consequently, the remounting hack must only be used for requests originating
- * from the old mount API and should be marked for full deprecation so it can be
- * turned off in a couple of years.
- *
- * The new mount API has no reason to support this hack.
+ * But, currently the util-linux mount command already utilizes the new mount
+ * API and is still setting fsconfig(FSCONFIG_SET_FLAG, "ro") no matter if it's
