"Still stands" means is impossible.

New to speedrunning?

Pannenkoek does have a few videos documenting stars that can be beaten with No Joystick Allowed strats (these are old and there are more on the secondary UncommentatedPannen channel but I don't see a playlist compiling them). A full run is definitely not possible, but at least some stars are doable.

"Still stands" means that there is no known way to achieve it. Not that it's known to be impossible.

Until the discovery of the virtual console glitch for BitFS a few years ago, the A button challenge "still stood" for all cases.
