Once there is a greater, functional Desktop Mode it will be considered even further. GrapheneOS enabled DisplayPort output for Pixel 8 when it is disabled in stock, which they'll likely enable elsewhere when a Desktop Mode is finished. Having a GrapheneOS smartphone able to work like a desktop with broad app support via VMs is a serious goal.
Having a Desktop Mode on GrapheneOS alone is a massive benefit and we hope to see it come to fruition with further Android updates.
