MicrosoftAre you able to clarify on your reference, under the Site Rename heading, to the UserVoice request regarding the change to the initial domain of an O365 tenant? What you described addresses URL adjustments further along in its path, not the root.
Site rename (available soon)
Site rename has been one of the most popular requests via https://sharepoint.uservoice.com/forums/329214-sites-and-collaboration/suggestions/13217277-enable-renaming-the-site-collection-urls– now in the SharePoint admin center you can rename site Urls. So for example, if you have a site https://contoso.sharepoint.com/sites/Develpment, using the SharePoint admin center you can rename the site Url to correct the incorrect spelling of “Development”.
The latest response from Matthew Carlson on the UserVoice request, on May 7, explicitly identified that work is being done to change the organization subdomain. He did end by noting the feature you mentioned above where renaming a site collection is part of that solution. It's a long time coming and I can appreciate the technical challenges surrounding it. Many of us are hopeful this will become a reality in the not-so-distant future.
This is looking like a big week and so happy it has made its return. Lots of exciting sessions outlined.
