Yes.  The only downside that comes to mind is it would no longer be easy to
build a particular subdir despite some other subdir that builds earlier
having an issue you don't care to tackle at the moment.

I welcome anyone who wants to give it a try.  Maintainability is more
important to us than performance, and there may be gremlins in our build
system that make it tricky, I haven't looked into it.  I have my hands full
with more pressing issues than overhauling the build system.
