<div dir="ltr">The other issue is that we work with applications that need to be able to rely on their PETSc being stable. If we can provide a 'dev' that is relatively stable, we can rapidly deliver new features, which encourages them to work more closely with us. If 'dev' is volatile, they will only use releases, in which case we have added close to a year of latency. I think that's bad.</div>

Pushing code that you believe to work, preferably with tests that show that it works in at least some case. This code is meaningful for other people to look at.

This is useless to push because it causes other people to step over your dead code and quick-fix your warnings.
