As stated in the last update, the ability to use multiple Teams accounts at the same time is being implemented in stages for Desktop. Faster tenant switching functionality on the Windows client has been rolled out to the public ring fully, and Mac will begin rolling out soon. Work is in progress on cross-tenant notification improvements, and support for multiple accounts on desktop will follow. We’ll keep you posted!
Note: The ability to use multiple Teams accounts at the same time is supported on iOS & Android today.

This should at the very least be a toggle-able option. I can see where large teams would want it off, but the organization I'm at works in much smaller teams (5-7 people). Team chat is essentially useless if the team isn't actively looking in it - which won't happen without notifications.
