To do this you have to keep a track of the definition history, so you

and such) where such a history must be recorded separately purely to
support FORGET. The TC did not wish to promote any particular
implementation method, this is why FORGET was demoted to an optional EXT
word and marked as obsolete in the '94 document.

The topic of MARKER vs. FORGET was discussed not too long ago
on c.l.f. For each claim that FORGET couldn't restore this or that,
wasn't efficient etc., supporters provided evidence to the contrary.
FORGET works and works well.

Fair enough, but that does not negate the fact that the '94 document marked FORGET as obsolete.
