Well, that's because you're only considering this use-case, where we
know the context and it's clear that building them in parallel is not
what you want.
But, if you consider something like:
make prog1 prog2 prog3 prog4
then it's clearly a design flaw if these programs are built serially.

There is no easy way to do this in GNU make today.
You can play some tricks with MAKECMDGOALS; something like this:
all: $(filter clean,$(MAKECMDGOALS))
clean::
check:: $(filter all,$(MAKECMDGOALS))
install:: $(filter check,$(MAKECMDGOALS))
