I figured you were going to say that.  It's not an issue.
C has gone through the same process.  It's Forth's time now.

Just introduce changes to the language slowly to allow programmers
time to fix the code.  E.g., C has eliminated implicit int's, added
void types, added typedef's, etc.  These and other issues require
either fixing the code, or adding options to the compiler to select
the version of the language.  IIRC, Forth had some words to tell
the user which version is in use.  Just add another to select the
wordset.  Isn't that already available in Forth?  I.e., vocabularies.
