Why not just use Google Spaces?

We heavily rely on Slack for communication and Google Workspace for emails, drive / sheets / docs etc. and Notion for PM.

With Slack being down, I quickly moved the entire team over to Google Spaces as a backup and now using it for 4-5 hours, I am wondering; why not just migrate over to it?

This would remove the need for another communication channel, instant access to documents, sheets, clear google meet / calendar integration etc.

Anyone else thinking the same? Seems like a perfect fit for companies relying on Google Workspace.
