Cannot Effectively Manage Channel Meetings and Replies

As an admin, I should be able to restrict who can schedule meetings within channels, especially the General channel.

I have a few Teams where only owners can post messages, but if a member schedules a meeting and adds the channel, it posts the meeting information to the channel and any member can then reply to it. This is alarming, especially when you have an entire company of 600 users in a Team. 

I even tried turning off the @ mentions for members and turning on moderation in a different channel, since you cannot moderate the General channel. Still, members were able to add these channels to meetings, which then posted the meeting info to the channels and members were allowed to comment on the meeting info... Very annoying. Microsoft needs to fix this ASAP.

See attached screenshots.

I also wish I could simply delete or hide the General channel from members. Better moderation settings could help with that too, but unfortunately, you can only add moderation to other created channels.
