@Mention a Team from Another Team
Has there been any new development on this being a feature?
No, and honestly don't think it will happen due to the member/permission discrepancies between Teams. However they have released Tagging (Targeted Communications) that can serve a similar purpose.
You can create a tag of the People from the other Team and then use that tag with @tag mention to mention that group.
So if you have a Team Shared by say IT and Marketing folks, and both have their own Teams. You can create a tag called Marketing in this shared Team. Then @MarketingTag in that shared Team to tag the marketing folks.
It's an additional item you will have to maintain membership with since there is no current integration with flow etc. But it's better than nothing and is a useful feature for mentioning other groups in a larger team.
Here is the article on the feature: https://docs.microsoft.com/en-us/microsoftteams/manage-tags
