[keycloak-user] password policy | Not (containing) Username

Hi, We would like to also prevent passwords *containing* the username, to also prevent passwords like Username_1980 The regular password policy "Not Username" only matches exact "username", rather than anything containing the username. Would it be possible to create a regex password policy to match a password *containing* the username? But I don't think this is possible..? Or perhaps I could file a feature request to change the current policy into "Not containing username"? MJ
