Like what? And is that a common use case?
Furniture is what comes to mind
Or just put down a nylon sheet, put the dirt on top, fold the nylon sheet over it and bind it down. … Buy a bus with removable carpet, then you can just hose it down as well.
Sure, you could do that, or you could use the right vehicle for the job.
There are many different rear door types and sliding side doors on the side that provide ample and easy access. This isn’t difficult or complicated.
Until you want a pallet of something. Would be nice if that van had a removable roof so they could just drop it in there 😉
What it comes down to is that trucks are versatile and people like them for it. If you don’t see utility in having open access, then that’s fine, but a lot of people do.
Resource management comes in many different flavors. Most computers allow you to use every resource it has at its disposal to accomplish a task (rendering graphics, processing workloads, gaming, etc), and that would really suck to have your system just decide it should nuke that process. It doesn’t really know what you prioritize, so Instead it runs and compromises the best it can until the dam breaks. But gaming is a little less of a gray area, its nearly always the main focus of the user, so its easy to draw a line there.
There are systems that are far more opinionated about resource usage that will reign in processes. Like iOS is a good example (The divide is usually desktop and mobile OSs). It prioritizes UI, battery life, and animation fluidity over any process and will kill anything that threatens it.
There are applications out there you can use to limit resource usage per app, so you can limit the resources of bloated browser engines that masquerade as native apps.
