Have a look at basically any other text-only messenging service/app. Slack, Signal, Threema, WhatsApp and dozens of other similar services started out as text-only and added voice/video chat afterward. None of their protocols were originally designed vor video chat and none of them supported it initially.
There’s even an IRC extension that allows video chat over IRC.
