For the sake of understanding you properly, if you can detect, remove and

No. A target might be defined, but might have or not have an associated
In some situations, it would be very useful to be able to override
already-defined rules for a target without having GNU make complaining
about the override.
For example, when writing a library of makefiles recipes, organized as
a set of makefile fragments to be included by a master
Even with GNU make as it stands, couldn't you emit your rules in the
form of variables, override them at will, and eval() them at the end?
E.g.

Perhaps the ability to detect if a target is defined and
