Just to point out that this request was also brought by external users/customers and both them and internal consumers will benefit from having the MW documentation being more verbose and clear.
Thanks!

I believe we should improve the Maintenance Windows page https://cloud.docs.scylladb.com/master/manage-clusters/maintenance-window to include what exactly are the maintenance operations performed during the MW and its implications.
For instance, should we expect degraded performance, potential downtime, or different SLAs for these periods? Something with a clear description, like:
Also, originally, MWs were meant to be used for operations that will require a cluster-wide RR (e.g. upgrade). However, I can see it being used more and more for scale-out/in operations when the customer doesn't normally give us a specific time, they usually agree to do it during MWs. @d-helios @ManjotS please confirm if this really is the use of maintenance windows.
