It would be great if LP can patch flag_secure which prevents taking screenshots and records in some apps.. and mock locations which allows apps to fake gps location (helps with some games like pokemon go)..
These patches aren't available for magisk modules because they require patching the framework.. but LP can do them because it can patch apks on the fly.. I know there are xposed modules that do this kind of thing but the xposed framework is known for putting a load on the system and that's why it isn't preferred by people..
