angela Is terminal out of alpha?
It is still experimental and not at all complete.
Release announcements can be found on the GrapheneOS web page and also in the on-device Info app.
As long as the VM launcher is hidden in Developer options and is discussed in release notes as "experimental" (example) it is still experimental.
Maybe it will be usable in a month... maybe sooner... maybe later... but when it is ready for general use that will be made very clear.
