The balance between securing all things O365 and securing the hybrid cloud
To add to the list, we have seen an increase in attacks via Teams. The first being attackers using a compromised account to add an external account to be a member of an existing O365 Teams account.  The other is attackers tricking users into installing applications into Teams environments which may undermine existing security controls, such as multi-factor authentication (MFA), and enable malicious action on behalf of the authorizing user.  So while the threat landscape seems to increase on a daily basis, we see customers putting more focus on identifying and stopping attacks in their hybrid cloud since that is typically the destination of the breach. And while there are ways to secure the entire threat landscape, SOCs typically don't have the capacity to secure every single thing nor the hours in a day to do so.
