of something from which you can recreate a system, and music export does not do that.

ah,ok, I look at any copying of something useful as a backup. In this case, it's just a backup of the artwork and information, not of the whole system.

If I wanted to transfer the downloaded additional data to a new system I would use export to single file and then import that file.

You trust your computer more than I do mine. One file, and the computer's in charge of sucking it back in? I get the creeps when the computer has too much power. I like having all the labelled folders, I can open them and see what's in there, I can read the nfo files.

Do you mean that you have an online system, scraped art for song artists from online sources, exported it, and can now also use it from an offline system that can only show local art?

Yep. Before your artist info folder, it was good for all the album artists. The "other" artists were all there, too, but no pictures (just a generic icon) or information. Now, using the artist info folder, they've got the lot.
