Not sure if it will help but maybe we can also post in Android's Issue Tracker thread so that Google support team will prioritize this?
Looking at the ticket in question: https://issuetracker.google.com/issues/227166806#comment8 Google assigned P4 priority to this issue and P4 is basically the lowest priority they have, described as "An issue that should be addressed eventually. Such an issue is not relevant to core organizational functions or the work of other teams, or else it relates only to the attractiveness or pleasantness of the system".
In other words, they don't seem to care about this as we can see they didn't do anything in the last 8 months.
Camera is the only thing I missed so dearly from Samsung.
