Does resetting SYS_AUTOSTART to 0 actually accomplish anything or should we just leave it alone to keep things simple (development workflows, avoiding unnecessary resets jumping between versions, etc)?

Resetting it to zero flags that the autostart wasn't loaded. When I talked to @bkueng he was stressing that this should be retained for the case someone updates but the airframe he used is gone from the new version. I remember I was once glad that I saw the ID go to zero in one of my tests. Not sure if that couldn't be solved even more user friendly e.g. by messageing the user that there's no airframe with the ID but not changing the parameter.

For reference this was introduced here: https://github.com/PX4/PX4-Autopilot/pull/13772/files#diff-c0c83e328e28cbd2f7c7ad46bbb6369024ed63daa3f9dc8cf89ac79125183e1dR82
I did not change it but am open to discussion. I feel it's more accessible to change now.

# Check parameter version and reset upon airframe configuration version mismatch.
# Reboot required because "param reset_all" would reset all "param set" lines from airframe.
