Currently, if a group has no label, a warning is produced. However, it's pretty common to use groups for organization and not just display. In that case, there's no value to a label. Whenever a user brings up that warning, it's to say that it's confusing. Recent example: https://forum.getodk.org/t/support-for-fields-groups-without-label-hint/57111

Any likely downsides? Do others see value in the warning?
