One day? Probably. No one is working on it. Can't be a timeline for something that isn't being worked on. Developers will need to step up as device maintainers.
The time required to develop the initial support for it won't be lower if it's started 6 months from now instead of being started today. It's not just going to materialize without having device maintainers for the device. Same with the Pixel 5 and also non-Pixel devices too.
