The only problem I see here is the checkuser-temporary-account right being assigned to this group. Per https://meta.wikimedia.org/wiki/Limits_to_configuration_changes that right is exclusively assigned as a stand-alone. Ukwiki admins are of course welcome to assign it to new arbitrators (through the "Temporary account IP viewers" group), though, which would do essentially the same thing, but including it in a group that can be manually assigned without a check for the legal requirements would be a prohibited change. I can, however, proceed with the user group with all other rights requested to be assigned, as nothing appears to prevent any of the remaining rights from being assigned to ArbCom members.

Removed ipinfo-view-full as well, as not permissible by IP address access policy (requires administrator, bureaucrat, checkuser/oversight, or global group access), implemented without ip viewing-related rights.
