After all GNU make is not "the reference implementation of an alpha build

than just a few O(n) lookups. You might find features like checkout
from RCS/SCCS version control via built-in rules which is obsolete stuff
since long ago, still everyone using GNU make today is paying for it with
maybe 80% of it's total CPU time, worldwide. (Try "make -r ..." to see
what I mean).
I have been using -r routinely with make for a long time. My system for
make does not use the built-in rules, but has its own pattern rules for
everything required.
