So if I set up my own style processing in order to override this behavior
(both the earliness and the use of the empty value) as you suggested to
Greg, would it be kosher to use the matcher-list style, or would I want to
use my own style name?

No; three have two, one has one:

    --show-defaults
    --show-omitted-dirs
    --show-transformed-names
    --show-stored-names

I'm still trying to formulate a question about why the default behavior
here is user friendly, but I'm having trouble.  I can understand the logic
of each step, but it doesn't seem like it's the right thing overall.

Thanks,
