I don't know what you mean by this. The input returned by REFILL can be 
accessed by executing SOURCE e.g.

: get-line  ( -- caddr u )  refill 0= throw source ;

get-line will return the input that REFILL obtained whether the current 
input source is from the console, a string, a block or a file. GET-LINE 
is a simple definition not a protocol.

What danger? Who says it is a system word - it's defined in the standard 
as a word to obtain text from the current input source independent of 
what that source might be. ISTM that this makes it more of a user word 
than a system word.

I'll get my green pot of paint out.

unless it's keyboard input because it can't - it hasn't been typed yet. 
In that case it should accept whatever the user types as the next line 
of input. That's what every other ANS Forth system I've tried does. I 
also think you'll find that other Forth systems that read the whole of 
an input file for compilation/interpretation will, if REFILL is 
executed, return the next line of text that would have been 
interpreted/compiled. If they don't they are not ANS Forth compliant - 
neither is ciforth which is why I say ciforth's REFILL tells a lie 
(unless of course it is truly at the end of the file).

its REFILL has nothing to do and just tells that

A user might want to do so e.g. a word has been defined using REFILL and 
the user wants to test it using the keyboard. Also a user might want 
keyboard input without having to use ACCEPT because WORD, PARSE or 
PARSE-NAME can be used on it which can't be directly done with whatever 
ACCEPT returns.

No, I think you are mis-interpreting what REFILL should do.

My core extension tests for SAVE-INPUT and RESTORE-INPUT rely on REFILL 
working correctly when the input source is a file or a string. Nobody 
has yet reported that as being a faulty test. Testing REFILL on console 
input can't be done automatically any more than it can for ACCEPT
