I don't see how that excuses anything. It certainly doesn't give harness developers an excuse to be disrespectful to their users. It shouldn't give harness developers any reason to not even try to produce a stable release with a well-designed UI instead of a janky mess that gains new bugs every time you try to use it.

There are contexts where "move fast and break things" can make sense, but usually not when it's other people's workflows that you're breaking.

Just how old do you think a category of software product needs to be before it's reasonable for users to start expecting professionalism from the developers?
