I don't know anyone who isn't optimising for development time in some way. That said, most frameworks don't provide any worthwhile error handling infrastructure, and it's a problem.
In a Jetpack Compose app I wrote, I created generic "error barrier" components, so that error messages display over relevant parts of the app, with just a few lines each time, timeouts included. I think this is the best approach, easy for developers and informative for users. Too many apps just ignore errors.
