I mean, it doesn't hurt much now because I don't use it except for storage. Although it did take up permanent residence in my bedroom hallway because it is too big to fit anywhere else in my house.
Yeah, I have a smaller scope (100 ED), but my SkyWatcher case is just taking up space on the floor of the bedroom. I forget (haven’t used it since the first weekend), but iirc the star diagonal has to be taken out to put the scope in its case - well, that’s a no-go right there for me for casual use. For storage, I just leave the telescope up mounted on its tripod with a dust cover over it. For transport, I take the telescope off the tripod, carry it out to the car and just lay it across the back seat, with various sundry items such as a blanket and pillow that’re usually back there, plus stuff I’m taking with me like my coat or jacket, my backpack, etc., wedged around it to stop it from rolling around. How much do I worry? — not one bit.
The main practical use case for the included case, the one I was excited about when I first saw it, would have been as an airline travel case — it looks like it’s suitable for air travel. However, when I got the case in hand, I saw that the aluminum panels are very thin — it’s not suitable at all as a flight case. The only other reason I could see for using it then would be a long road trip in our small vehicle, but the mentioned soft sides don’t really offer much protection for stacking stuff on top of it and like you said, it takes up extra room, so it may literally never get used. Maybe if I give up astronomy for a few years, it’ll be used for storing the scope in a closet whilst getting the giant case out of the way at the same time...
Frankly, I wish it would just disappear. But I can’t bring myself to throw it out as it looks neat and, like the included eyepiece I don’t use, is part of a complete set for re-sale. So, it lays on the floor of my small spare bedroom uselessly taking up space
