Certus I see, thanks. But the issue opened in 2021, three years gone and still done nothing. Probably it will never be implemented if GOS management is still not interested doing this. The issue may be there for few years more.
They are interested in implementing it, but yeah, it might be a few more years until we have it. As is unfortunately the case with all security and privacy focused projects, there are way too few developers, and we have to accept way too many weaknesses for way too long. I am certain the GrapheneOS team are doing their absolute best, but there are so many other security and privacy issues that need to be attended to too, this isn't even among the top most urgent ones, so I guess we have to wait for a while.
