Strongly depends on the company. I have done this exact thing several times when something was critical and it was actually noted as one of the reasons they told me as to why I got my last promotion. Something like “staying focused on the issue at hand while respectfully managing the pushback from the business while still moving ahead with the urgent fix.”

Basically I told the business to shove it in a very polite way and fixed the issue.

The invention of sliced bread may function well as a specific point in time after which inventions happen, but sliced bread as an “invention” caused a chain reaction that changed the composition of the bread available in stores, at least in the US, resulting in the bread tasting like shit. So I would not classify it as a great invention at all, rather for what it was: a successful marketing campaign.
