Fixing conflicts for the backports can take a lot of time and often requires very skilled work to do it properly as it will for one of the patches this month. Doing an extra OS release also takes a lot of our resources. It takes a lot of local compute time and testing effort.
This shouldn't be something we need to spend resources on because we should know the official release schedule and should have early access. It's harming Android more than GrapheneOS since these kinds of artificial issues inflicted on us are exactly why we stopped contributing.
