I think you are right about "EACH of those 'other words'".
I'm not sure I agree with new words.  If the new words only used
$CREATE DOES>, then the user(s) of the new words could prefix them with
a WORD (or whatever is appropriate for leaving on the stack what $CREATE
expects).

Agreed.  On both counts.

Boy, that sounds really familiar.  Was it written up anywhere (FD, etc?)?
[The obvious question:  Can QUOTE-TO be done in BASIS/dpANS-Forth?]
