Seems weird to be honest. I would agree on removing personal Teams from new Windows installations, but if you are locked in Microsoft 365 environment it is very unlikely you will not use Teams due to how well it integrates with whole ecosystem.
It's almost as asking to unbundle Outlook because Thunderbird exists.
It doesn't really integrate that well, but it's included with most enterprise licenses so what company is going to pay for another option when they get it for "free".
It integrates very well, and gets better over time. You don’t need Outlook Calendar anymore, the OneDrive portion makes more sense than the actual website it’s pulling from, and the new Planner app is actually decent compared to the old one that was buggy af inside of Teams.
