That's how you slow down development to a crawl
Yeah, lets just start building a house and don't wait for architects to finish the blueprints :) They just slowing us down with all that thinking things through stuff.
That's fine. Right is better than now.
I don't see a problem with this. The problem with "move fast and break things" isn't the moving fast part, it's the trail of broken things that no one bothers to fix. When those broken things affect people's wallets, that's when we have problems.
