But while it can share a desktop view I didn't think it allowed control?!? Man, this could be a family support game changer...
Edit:
requires Electron app it seems. https://github.com/jitsi/jitsi-meet-electron/releases
Was on HN, some comments suggest the Electron app bundles Chromium.(Not sure if all Electron apps do this, I know nothing about Electron..yet.) https://news.ycombinator.com/item?id=22830846
Edit sub basement 2: Yes, Electron apps include Chromium. "it combines the Chromium rendering engine and the Node.js runtime."
"Should local desktop control be a feature that can be enabled through web browsers for users who choose to use it with certain sites?" Eh, this is not so clear. What if by some magical turn of events Zoom decided on a drunken whim that user privacy is very important, and strongly encouraged use of web over desktop, should they just axe that feature? Back in reality, Zoom couldn't even consider that course of action until the web supports it.
Maybe do it by requiring users to install an extension that's granted remote desktop permission for a particular site. Which would at least allow the extension to be reviewed and audited.
If it breaks a lot we must have been exceptionally lucky for none of us to have problems.

For simple remote support, you shouldn't be doing that anyway.
