Host Server Maintenance

I've seen similar posts from a long time ago so I thought I should bring it back up. 
There should be a maintenance mode you can put your discord server in so that specific roles can’t interact for a fixed amount of time or undefined amount of time.

You can set a custom message, for example; “This server is currently testing bots/channels.” And under the message could be a reopening date and time. 
To know if a server is undergoing maintenance, there could be a yellow “!” symbol showing that it is inaccessible to your role.

There are ways to do this, but they aren’t embedded into Discord itself, you have to either do it manually or add a bot that can. It would be a nice quality of life update for moderators, admins, and owners alike. 
Please consider adding this feature to your app at a later date. Thanks for reading and let me know what you think! :)
