How many are you thinking about having in the game at the same time, GM Miles? I've had 18 simultaneous players in a game during Roll20CON last year. We were not using Roll20 audio/video, and I had the players along the bottom set to "Names Only". There were about 3-4 lines of names.
No wonder your brain looks like that Gold. ;-P
As a DM, I couldn't imagine trying to communicate with that many players or as a player, trying to communicate my actions when 17 other player's want the same... I think I would have to start the game with an initiative roll and march through the entire session one character at a time.
Our group runs 4-5 plus a GM using either roll20 voice chat or Discord depending how finicky roll20's audio is feeling. We are running Pathfinder using the Community Sheet. It's one of the BIGGEST sheets on roll20 so depending on the number of npc's and spellcasters that want to include every spell in the known world on the sheet(don't do that BTW), the game can get sluggish pretty fast. I would think other games/sheet's would handle larger numbers of players better.
