User and group mount options for ext filesystems

Given that UID/GID data is largely useless and a nuissance for most removable media, why not let the user specify that they do not want UID/GID data for a given file system when the file system is created. Save a value in the superblock indicating a UID/GID-less file system. The permissions can be handled the same as is done for VFAT in that case (controlled by mount options and defaulting to root.) This way a) developers don't need to worry about deciding which device is "removable", the user specifies the behavior they want for the evice and b) any determination of how the device is to be handled is made once when the file system is created rather than every time it is mounted.
