Just because they're invalid when make starts doesn't mean they will be
when make searches for them.
Also, VPATH is often used intentionally in situations where one or more
of the directories on VPATH does not exist; that's one of its use cases
("pick the first one where the source exists").

You can, of course, do it yourself; something like:
_nonexistent_vpath := $(filter $(VPATH),$(wildcard $(VPATH)))
ifdef _nonexistent_vpath
$(error These VPATH directories do not exist: $(_nonexistent_vpath))
endif
Note, not tested but you get the idea anyway... if you use ":" separated
VPATH or want to allow for that you should do $(subst :, ,$(VPATH))
inside the wildcard function.
