The only case it would increase power consumption in practice is if you do something like a 2 hour video encode using poorly optimized software which runs less efficiently due to hardened_malloc, hardware memory tagging, etc. which have per-app toggles available.
Our use of full ahead-of-time compilation for apps with the usual just-in-time compilation disabled decreases runtime battery usage at runtime while needing more power after an update for recompilation (optimizing apps).
