In discord you see a room of people in voice chat which features drop in drop out.

You can them independently drop in and drop out of any text chat room.

The most common way to share text channel based content is to say "hey I'm posting an image in voice chat check it out"

The important part here is making voice the first class primary communication while not prohibiting the use of any text channels because there is no coupling.

Complete independence is better than coupling imo.

Separation can be done with permissions for both a single text and voice channel.

Also as long as someone has access to the voice channel they have access to the video channel of all active live streams.

I think that just elaborates on what was said previously, it's up to you how to set it up if you want the coupling or not.
