I did not think of that. So much for "obvious".

On IA-32 and AMD-64, you would get a big slowdown for many programs
unless you separate the generated native code from the threaded code
(which requires additional work that has not made it into a number of
native code systems yet, 16 years after the issue became known).

I don't think that adding a code field makes a significant difference.
1 constant 1 generates
dw *+cell
mov r0, #1
push r0
next
or perhaps
dw *+cell
mov r0, #1
jmp push
or something similar.
