In order not to be deleted by mistake by a client, it is possible to move this Plugin to the “mu-plugins” directory without losing its functionality.
It's not a big deal.. if it was deleted the next user action to interact with Wordpress from the Enhance panel will just re-install it. This is all done via CLI.
I would prefer it if the login would work without an additional plugin. Most customers don't expect an additional plugin to be installed and don't know what it is when they see it in the backend. This causes additional support effort.
