Sorry, I didn't explain well.

The patches are related. They are updates based on feedback, partial
failure or improvement.

They aren't bulk pushes (whatever that means). They are updates on a single
changeset.

Why do people send multiple patches per push? That's the right question to
ask.

And the answer is: to improve the previous patch.

Hence my question. If a patch has partially failed, or I got feedback to
improve it, or (insert reason here), and I want to push an update, why
should the previous patch still build when it's not necessary?

Hope this makes sense.

Obviously I'm not doing that. Obviously.
