To avoid these problems I am using an overlay FS (just reads from flash and writes to memory) and after a reboot all changes are gone. That might not be suitable for everyone but works great for stuff like mqtt brokers or devices which pull their configuration on boot.

This is how I am using my Raspberry Pi (running Pi-hole) too: overlayFS. It means that I lost the statistics after a reboot, but it also mean that I don't care if the power in the house is suddenly lost either. I also enabled watchdog support so my Raspberry Pi is probably the most reliable part of my network.

Same here. I run temperature monitors on mine. Every five minutes a cron-job copies data to a /boot subdirectory which is still r/w. On power loss, the most I can lose is those five minutes.
