ISTM vendors saw ANS-Forth as a new era and took the opportunity to return
to symmetric.  This in contrast to a TC that was bending over backwards to
allow vendors to retain what they previously had.

DX-Forth followed a similar trajectory beginning as a Forth-83 system
with floored division in the early 90's.  By 1997 I had dropped CP/M and
potentially forth too.  I flirted with Pascal and Delphi but quickly
realized such things were no longer for me.  I missed the joy and
frustration of developing my own tools.  DX-Forth was ported to DOS in
early 2000's.  Most Intel based forths were by then symmetric and it
was simpler.  The choice was clear.  When a decade later DX-Forth for
CP/M was dusted off and brought up to spec, it was made symmetric too.
There was never any regret.  Indeed it was relief.  In hindsight floored
looked like a cult that had lost its following.  In 83 I had drunk the
kool-aid along with everyone else...
