I'm not sure I agree. I believe that at the very least, there will be a community manager or similar that is reading the posts on the forums and communicating back to the dev team.
What you need to bear in mind though s that this community manager is possibly managing the same for a whole bunch of other games as well, and possibly involved in promoting at events.
Additionally, development resource is limited, and the direction taken by the production team will be mandated based on a whole bunch of other factors. Anyone around long enough will remember the game went through a very interesting early history, with ownership changing hands (and no doubt some internal politics there) and then the spintires to mudrunner rework. I'm sure in the middle of this there were a number of massive changes in the dev teams and code ownership which required significant rework. Then the porting to PS/XB and following that Nintendo. Each of these would require a significant review of the code for porting. Also likely a significant need to review the code structure so that development and porting can be done relatively painlessly from the same code stream, rather than trying to manage multiple parallel code streams. I wouldn't be surprised if much of the reason that changes weren't quickly implemented is because nobody wanted to revisit the code.
All this means that a finite development resource had enough on their plates with their given strategic release plans that there was likely little time to review anything non-critical.
MR2 will give the dev an opportunity to start from scratch, taking what is good and usable from MR and reworking it into a development/deployment schema that is manageable based on their new release strategies. Or at least this is what they SHOULD be doing. Bear in mind that the challenge still remains that there is likely a finite development resource and time limit and a significant amount of work to do. One of the key issues that will still exist is how they manage the PC/Console divide, especially when you have consoles like the Switch that are significantly under powered compared to the next gen 4k consoles and todays best gamer PCs. They need to provide best experience, but do so without damaging the playability when ported to lower performance devices.
My only wishes is that they focus on features that extend the lifetime of the gameplay and stay away from the new trend of in game purchases. Bug fixes and Playability please!!!!!
