As you said, marking whole threads as read would be a case I would use
regularly. If anyone is willing to add that feature, I would be glad.

Even the second case would be possible, just not as elegant (but still
better than my shell construct)

notmuch tag --thread +kill -- tag:kill
notmuch tag -kill -- tag:kill and not date:30days..
