I personally hate the “it’s temporary” excuse we developers often have.
My goal is zero crashes, ever; at any time during development. The same with memory leaks or severely anomalous behavior.
It's an old-fashioned way of working that results in basically zero tech debt.
I'm allergic to debt, of any kind.
The nice thing about working this way, is you get incredibly well-formed UX, and you don't have that awful "QA surprise," at the end of the project.
It also goes a lot faster than you might think, as bugs get fixed close to the time of their creation.
