"Horrific" is massive hyperbole, at least for my use case. (I actually use a GCP preemptible instance in this manner for a personal project, and spot instances will have the same shutoff risk.) I edit application code on my (relatively underpowered) laptop, and automatically mirror it to the instance where the running services picks up any changes, and recompiles and relaunches as needed. It's a fairly chunky app code-wise so moving the CPU usage off of my laptop is very helpful. When and if the instance shuts off early, I just relaunch it and reconnect. This amounts to one click of the mouse in the GCP UI, one locally run terminal command to connect, and one remote terminal command to (re)start my app. No work lost, and the cost savings are worth the minor inconvenience. Usually the instances last the full 24 hours anyway, and I usually shut it down when I'm done working, so interruptions are very rare. I can understand that in the context of a larger company with more resources, a dev would be put off by this. But it works very well for my uses.
