Hi Joel Mehr - this is good feedback, thank you! The Known issues list (https://learn.microsoft.com/microsoftteams/new-teams-known-issues#what-features-are-changing) is where folks can see what gaps there may still be. The features that aren't at full parity yet are just a handful of low usage features (based on metrics), so we didn't detail them, and the major ones were support for VDI and gov clouds.

As for the adoption hub site, I'll talk to the team about revamping that section, or at least linking out to the Known issues list.
