While it's a legit metadata privacy vulnerability, it doesn't close a much bigger hole that already exists. (Close it, if you can, of course.)

Almost every carrier can triangulate a handset in an area with multiple towers without help of the handset using relative signal strength to each seen towers and data processing. This is how most police in most jurisdictions are able to find an active handset within ~100m given only a phone number. Don't think carriers in some countries aren't constantly logging that approximate and precise queried location metadata and selling it to data brokers.

The only method to prevent continuously location tracking is to disconnect a handset from the cellular network by attenuating the signal with a blocking bag, antenna disconnection, or real power off. The lack cellular network connectivity may be extremely inconvenient by defeating the purpose of a phone. There are situations where someone doesn't want to power down their phone but does want to be RF clean where a Faraday bag would be a good idea(tm).
