I also think that it's silly.  After the patch applied,

(gnus-parse-format "%A" '((?A "ABCDE   " ?s)))
=> (concat "ABCDE   ")

(gnus-parse-format "%A" '((?A "ABCDE   " ?s)) t)
=> "ABCDE"

Future Gnus developers will be troubled with the difference of the
results.  Also, this change makes gnus-parse-simple-format specific for
rendering *Group* and *Summary* lines.  That's a layer breakage.

I think Katsumi's first approach is even better.
