Sounds sensible.  The attribute assignment was designed to purely
depend on paths and not contents, so it might be a bit awkwarad to
implement, but it should be doable.

The original request, as I understand the clarification posted
upthread, is not "submodules are uninteresting", but is "we want
regular files" (and we postprocess further the output), so such a
"mode" (pseudo-)attribute that is automatically populated would be a
better fit anyway.  With the current system, they can already do:

    git ls-files -s ':(exclude)*.png' ':(exclude)*.ico)' |
    sed -n -e 's/^100[76][54][54] [0-9a-f]* 0       //p' |
    xargs dos2unix

(cf. <9cc98ca3-bdc5-61bf-450a-99bb47673d6c@gmail.com>)

and with such an auto-pseudo-attribute, presumably something along
this line would work, removing the need for the intermediate filter:

    git ls-files \
	':(attr:mode=100755)' ':(attr:mode=100644)' \
	':(exclude)*.png' ':(exclude)*.ico' |
    xargs dos2unix
