I didn't even think of that! That prompts the idea, why is this entry point necessary at all? If you have Smash Bros and a N3DS, Smashbroshax is pretty easy to perform (as long as you have access to Linux in some way shape or form, including boot-able disks), and it's a standalone exploit, no need for another. (And again, Smash is awesome, so why would you want to lose the ability to play it?)
Pros:
1.) No need for Linux or any compatible hardware.
2.) Faster (by a few seconds).
3.) Probably more reliable.
Cons:
1.) Cannot play Smash Bros anymore.
2.) Depends on having access to another entry point.
3.) Makes you look like less of a haxxer.
