Agreed, but the driver typically makes decisions about forming commands
based on flags provided and suffixes to files.

(at least for the two I am familiar with) it does not do dependency analysis
nor does it have any need to parse the source.

I suspect it would be better to place the ‘trivial build’ system as a separate
entity (perhaps invoked by the driver) rather than upgunning the driver to
have those properties.
