Problem: Currently, Proton Meet has permanent rooms that are great for recurring workflows (e.g., schedule management with EHR systems like Sessions Health). However, they lack a proper gatekeeper function. For users working under HIPAA regulations, a permanent link with only password gating is a liability. If a client joins five minutes early while a previous session is still active, they could accidentally "crash" a private meeting. This creates a significant privacy breach risk.

Proposal: Introduce a Waiting Room / Lobby feature specifically for permanent rooms. The host receives a notification when someone attempts to join. Pending joiners remain in a "holding state" with a customizable message until the host manually admits them. Ideally, this would include a toggle ability allowing hosts to turn the Waiting Room on or off in the meeting settings.

While Proton has a significant advantage with privacy by design instead of by promise, this current limitations is unfortunately enough to prevent Proton Meet adoption for this use case.
