The signature pref cannot be disabled using $wgHiddenPrefs?

'fancysig' will disable the fancy sig but not the complete fieldset
"signature".

This works to disable the form, but I had to dig around in the source to find it:

$wgHiddenPrefs[] = 'nickname';

At minimum, the documentation should be updated to reflect this, or the 'nickname' field should be changed to 'signature' or something more closely matching the expected nomenclature

Preference names are documented at https://www.mediawiki.org/wiki/Manual:$wgDefaultUserOptions#Available_preferences but the row for "nickname" is empty...
