However, we also have to consider this: in some cases, when the uncompressed form is hundreds of times larger than the compressed form, the former may be really unpractical to handle.

Well: in those cases, the preferred form for making further modifications is that *compressed* form, which is consequently the actual source!
It's possible that the compressed form can be impractical for some purposes but not others.
