As per the Message Center Post MC187289 we have started to roll out Site Swap. This is a new PowerShell cmdlet Invoke-SPOSiteSwap that will enable you to swap your existing root site with a Communication Site. For further information please refer to https://aka.ms/SiteSwap.
Thanks for your feedback! Just a note to let you know that we’re building your suggestion now. We plan to increase availability to this feature as we continue improving the tech, and ensuring a smooth experience across Office 365 following the URL changes in SharePoint Online.
