It used an extra cell in every word defined with <BUILDS.

Not sure what you mean.  If you refer to my last paragraph, what I
mean is that you can do

: doesa does> drop ." a" ;
: doesb does> drop ." b" ;
<builds foo
doesa
foo \ prints "a"
doesb
foo \ prints "b"
doesa
foo \ prints "a" again

in fig-Forth, and the proposal is for a word that cannot do this.
