Could Microsoft Teams be about to let you set different channels as the default, replacing General?

I noticed a new addition to the Microsoft Graph API, as detailed in the Changelog for June:

Addition - beta, v1.0 - Added primaryChannel navigation property to team resource type

This new property is available in both beta and v 1.0 and there is a documentation page for it as well:

Why is this interesting? Well, today, you can’t chose the “primaryChannel”, so it’s not immediately clear why there would be an API call to get it – as it’s always going to be “General”. In fact, the description for the call even points this out.

Perhaps this property is here to prevent developers from needing to hard-code “General” into their code base. Maybe it’s to support Teams tenants that span multiple regions where the General channel will actually be titled in the local language. Or, perhaps it’s an early indication that, in the future, you will be able to change the name of the General channel – meaning that an API call like this will be needed. There is a UserVoice for “Rename General channel” with nearly 4,000 votes.
