The functionality to make it possible to change the name of an O365 tenant, especially with Sharepoint Online in mind, is being planned. There is no ETA at this time though.
Hi, As announced at Ignite Sep 2020, we will be making this functionality available as an open source tool by the end of the year. It can be used to pull in 1 or more security groups (nested or not) to drive the membership of a M365 Group. The membership will be pulled in as a flat list and kept in sync with the security group membership. However, if you have a pressing need for it before then, please reach out to GMMSupport@service.microsoft.com for a download of the tool. There is no support provided for the tool from Microsoft, other than answering any question around how we use it here.

How is such a fundamental part of domain management missing from 365. We really need this feature!
