 Additionally, there isn't a notification on the player side that they are gagged, unlike permanent mutes and gags, so the only indication that they are gagged on their end is through the command message. If they're disconnected when they get muted or gagged, they can't see this.

Solely for this reason I personally feel like it isn't worth the time. Might end up creating more trouble then it's worth because there are honestly very few times you even need to gag/mute someone who isn't on the server. In fact there are basically no reasons lol.
