Allow change to base url
Allow organizations to change their base URL in case the company name changes or for whatever reason the base URL becomes inappropriate. (eg contso.sharepoint.com to company.sharpoint.com)
Being able to do this without having to re-create the tenancy from scratch would be invaluable.
I would really like to see this implemented. The URL was incorrectly created before I joined. It doesn't affect us, but the url is untidy and triggers my OCD.
