We should decide whether to delete the maintenance script, or later move it to the RemovePII extension as an alternative way to delete data. It actually currently in its current state removes much less information then the extension, and is somewhat difficult to maintain both the extension's job and the maintenance script. Simply deleting it may be best, as it is obsolete now with the RemovePII extension. It's also less reliable then the extension as it requires a locally attached account to meta, and doesn't delete all the information the extension does. Since the extension has been performing sufficiently removing it at this point seems like an okay action.
Assigned to myself as whatever action is decided upon I will work on doing. It's simple to complete if we are just deleting it but to move it will take more time as it will need rewrote to be up-to-date in MediaWiki standards, and to delete the same information as the RemovePII job. Regardless I don't think we should keep it in MirahezeMagic.
