It would be interesting to see how open to refinement suggestions the grapheneOS team is now.
In the past, my observations was that suggestions like this were typically met with open hostility based on lack of developer timenwith responses like "write it yourself"...
I understand developer pressure and prioritisation (I'm a product manager!) so "it is on the backlog" is totally an acceptable option!
It will be interesting to see what changes with the change of project leadership.
