I have seen mole125's configs, and though it's pretty cool, it's not really the intended way to write scripts. I wonder how it will be to maintain. I know lillfilurens generic checker is something he regrets, and that he rather had several short and easy to understand scripts.
Regardless, What kind of case requires such big config? Of course the config can be increased, it's not a huge amount of work, but may be a few places to change it in. But the idea is that the configs should be fairly short so that they are readable as well.
They will then of course be less readable if keywords like type and size becomes t and s (and so on) to reduce the size. But in my mind, in the cases I have thought about, 4 kB is quite a lot of config data.
