> Development mode does not serve html files like production builds do. The site behaves differently in that mode, and some issues only happen in actual builds. When you encounter one such issue, the feedback loop becomes "full build for every change" == ~10min of waiting to try every single change. This is a HUGE productivity killer.

This got me so many times. I was frustrated enough that I set up a headless chrome prerenderer to snapshot my gatsby-built site before every single deploy just so I could verify the html diff to make sure my site looked correct still.

The trust issues alone were enough to make me switch off of it.
