Very nice!

I know this is just to demonstrate, but just for interest sake, if there are already other protocols enabled,

set_config('webserviceprotocols', 'rest');

will disable them. That is why I do:

$enabledprotocols = get_config('core', 'webserviceprotocols');
if (stripos($enabledprotocols, 'rest') === false) {
    set_config('webserviceprotocols', $enabledprotocols . ',rest');
}

Yes, that is better code.

Is this what you are looking for?

According to documentation the webservice user should use the "webservice" auth method:
https://docs.moodle.org/500/en/Web_services_authentication

So the create_user function needs the additional parameter 'auth' => 'webservice'!

The purpose is to avoid setting 'policyagreed' => 1 for the webservice user:
https://github.com/moodle/moodle/blob/MOODLE_500_STABLE/lib/moodlelib.php#L2465

Fun fact: the "webservice" auth method can be used without activating it.
