No.  A target might be defined, but might have or not have an associated
recipe.  I was speaking only about changing such associated recipe, which
GNU make is apparently able to do right today, albeit unconditionally
printing a warning when it does so.  It's because of this pre-existing
ability that I suspect and hope it would be feasible to implement my
originally proposed feature.

Actually, we can already add targets *but not* remove nor detect them,
and we can already add recipes *and* override them (we just cannot do
so avoiding warnings), but OTOH we cannot detect (not that I know of).
