It is mandatory... the system knows to append an X to any two-character
device name

Most utilities and user applications know to .FETCH device drivers they
need in order to do their task.  After they are done, the drivers are
.RELEAsed.  If they are LOADed before the program is executed, a .FETCH
and .RELEA are no-ops.

If they aren't loaded and aren't .FETCHed, then they simply are not in
memory.
