I think the main problem is that for deployments of any scale jitsi-videobridge really needs a dedicated host, with the jitsi-meet component installed separately. The former is the streaming server, while meet only provides the front end.
Unfortunately the install route most people go for is the semi-automated single-host deployment. Their quick install all lives within docker and is very straightforward.
The detailed manual install which lets you deploy the components separately is going to put off any newcomers quite quickly.
