In our space, I am the overseeing admin that creates 95% of our lists. When I share a list with a Team, the whole team gets notified. If they aren't related to that project, it causes confusion and I'll get emails asking whether they need to do something. I don't want to rearrange how my Teams are set up, but it would be nice to disable notifications when making updates to Sharing & Permissions, so I can just email those involved and say "it's ready now!"
