I think that is a misassumption, especially on aircraft. The feedback was most likely collected internally. There might be a backlog dedicated to aircraft which includes most to all bugs. The topic over here might have been closed as there is no work actively being done for the MSFS 2020 version of the aircraft and the improvements will go into their MSFS 2024 version.
HOWEVER that does not automatically mean these improvements will not come to MSFS2020 - as Jörg Neumann told the new aircraft may be backported if feasible (last developer stream about FFX).
On the F/A-18E and the C172 we were already able to see that especially the virtual cockpits were completely reworked and improved in the technical alpha. While these were obviously still WIP it might be that especially the interiors can be ported back and will be available on “the old” version of the sim. In one go they could also fix some of the systems.
No guarantees however, that’s just based on what I saw and what was told.
Understandable that this feels pretty inconvenient but usually it’s devs working on these items - and devs are not best in communicating quite sometimes
I also sometimes comment on internal user stories after their closure to at least shortly explain what was done or why something was rejected so someone can at least later see more specifics.
The moderators over here usually also only see the status of the internal story and can only get additional information after asking people with a different level of access to the stories details.
