Right, but you have to have enough disk space to hold it, which is my

If I have a 500M archive holding a 100M archive holding a tiny file I
want, I need 100M of temporary space to get the tiny file without
extract-to-stdout.  With extract-to-stdout, I don't.

...huh?  You appear to be assuming that the idea of extracting a file,
even to stdout, is to put the file's contents on disk.
Extract-to-stdout is not just about file names; it's also about not
having to store the whole file at once.
