FWIW, I also write my build systems so that they build correctly no
matter whether or which intermediate files are missing. IMO that's the
underlying philosophy of make. 

Having to rely on "clean" builds when incremental builds could do the
job just fine is IMO either an artifact of an insufficient build system
or a result of a bug (or missing feature) in make.
