I love the idea about compiler checking for unused variables in production, and that it's strict and not a warning that can be ignored merrily merrily, gently down the stream! :) We found a few cases in TigerBeetle where some nasty bugs would have been detected and prevented by this. Some of these were at the entry point to a function, where the function failed to check all the pre-conditions and was ignoring some of the API interface, and others were where we were calculating some of the derived buffers we would need, but then never use them, using the original buffer incorrectly instead.
