FYI: Unguided rockets still need to be targeted, you do this by aiming them and adjusting your aim after you make a shot can be done more reliably if you know where your rocket landed. That still requires your rockets to be of reasonably consistent build quality (which I have no data on) but it's been the same ever since artillery was first invented.
They just don't need Iran's intelligence to tell them where the existing targets are (that you can see announced on social media from time to time, eg. "we targeted Tel-Aviv as reprisal for killing civilians") and landing sites are also quite often reported all over TV and social media.
What this will achieve:
- information supremacy re. what goes out of Gaza
- makes it harder for reporters to do their job
- makes it impossible for the people who happen to live there to stay in touch with the rest of the world
