Rewrites are super risky and the subject of classic articles.


(NB: Firefox might not exist today if not for that rewrite.  But they
probably would have done better at retaining market share and thus had
more money for incremental refactoring had they worked incrementally.)

I'm highly skeptical that a rewrite is appropriate for PETSc.  Could a
second implementation language be introduced?  Perhaps, with an
appropriate plan.
