pit2p Any updates team?
The way to check whether there are updates is via the issue page (link above). If you are signed in to a GitHub account, there is a "Subscribe" button that will send alerts if changes occur. And near the top of the page there is a "Thumbs up" button people can use to express interest.
The developers do not want people to post "I want this too!" comments, because those generate annoying messages to the developers and clutter the comment area. If those comments show up it is likely that the issue will be locked, which will make it harder for people to contribute.
Please note that I do not speak for the GrapheneOS project.
