I am still baffled as why these thumbnails have to be produced in the first
place. A proof/contact sheet, some sort of project, what?

Does it matter?

yes.

If there is some odd reason to produce them, which has yet to be explained,
why would the concept of ³quality² be attached to thumbnails of all
things?

I have been doing this digital photography thing for some time, and I have
yet to have the need to produce a thumbnail of any quality.

Yes, you do. Any JPG generation has a "quality". It can be "one", so
very bad, or it can be "a hundred", so as best as can be, or any number
in between. Any jpg generated or changed has a quality number. You
choose the number, or you let the software decide.

that doesn't answer the question.
