I don't think so. The requirement to have FORTH-WORDLIST and SET-ORDER
means that you run the system normally after using this, including the
repl QUIT.
The intention of the standard that the minimum search order contains
a method to get the system under control. `FORTH' is way better than
manipulations with wordlists.
I cheated in ciforth. FORTH puts the FORTH-WORDLIST on top and is
a regular vocabulary/namespace.
 In fact it is equivalent to
 : FORTH GET-ORDER 1+ >R FORTH-WORDLIST R>  SET-ORDER ;

So the ONLY namespace contains prefixes (handles numbers and strings)
and the word FORTH to recover.
FORTH and ONLY are named wordlist/ vocabularies.

To seal off in ciforth you can do:
'FORTH HIDDEN ONLY
From now on only numbers and strings are recognized.
