Listings generated from Special:Prefixindex and Special:Allpages tend to be messy, hard to
read, and unneccessary lengthy when many subpages are listed.
I suggest a checkbox: "[ ] exclude subpages"
or a pulldown or number input field: "include subpages up to level [___]".
in order to make listings more usable.
Arguably, the preset could be, not to include subpages, but although I usually would not want
them listed, my preference is to include them all, so as not to change default behaviour for
those doing nothing, and not to break programs using the pages.
