Do not want to argue about anything or start a pointless debate since Devs will always do things their own way and I do support this concept fully.
That being said, I just want to share my personal opinion on how I feel about the new look recently been given to the Manufacturer, to let Devs know how things are perceived on the other side of the "barricade".(https://imgur.com/a/YcXUyqy)
The new model gives more visibility to animations and it kinda pays off the work put into it but, purely considering the machine as a whole,I do really prefer the previous design. Since it was already announced an Mk2 version, maybe, I would have opted to change the new not-yet-introduced one (if really that necessary) instead of changing the already working Mk1; also because it comes with noticeable different size/encumbrance which is quite a sensible topic for all those players that might be reluctant to adjust huge factories if not start anew to fit the new model. Just for clarity, I do not think this is the same "issue" as occured for the model swap/change/update to the Nuclear Power Plant as I consider that model as part of "outdoor machinery" while other models are more likely to be encased in walls (it all comes down to personal taste and play-style indeed, but still)
