Provide option to convert existing site to communication site
For customers who are trying to completely modernize their large SharePoint implementations, it should be possible to convert an existing site collection to use the communication site template.
It can simply be a powershell command that applies all the features/etc. it needs.
It doesn't need to change existing content, just apply the styles and create the typical landing page for a communication site.
It'll make it easier to adopt upcoming features (like adding sites to hubs, etc.)
This needs to be done, asap. MS are you sleeping?
