And what we're getting at is that you can already plonk a chunk loader down next to a computer. Or anywhere in the same chunk, really, or even
further away depending on the abilities of that particular loader. (Though I'm a little curious why you'd want to chunk load a score board - what good is updating it if there's no one there to look at it?)
Adding a chunk loader block to ComputerCraft, specifically, is a bit impractical. Suggesting it is a bit akin to requesting that ComputerCraft bring along its own version of, say, barrels - you can already get them elsewhere, and they've got nothing to do with computing. If ComputerCraft should add them, why shouldn't
every mod add them? And why
shouldn't every mod add every other feature other mods already bring to the table?
To be clear, all peripherals for computers still take up a the space of a block beside their computers. Placing a regular chunk loader next to a computer is by no means less space-efficient then any current peripheral.
I tend to use
ChickenChunks for chunk loading. They require no fuel (unlike eg World Anchors), their range (and the shape thereof) is configurable, and for a handful of extra ender pearls the full loaders can be converted to a bunch of spot loaders (which only load a single chunk, but that's often all you want for outposts and whatnot).
