The same reason why none of us have discovered the cure for cancer. Or a method of travelling back in time. Or turn lead to gold in 3 steps. Or... or...Why didn't they come out with another exploit?
This team obviously is small and sucks because they announced the thing 6 weeks ago and still can't get newer firmwares working.
... yeah, on their main page update, they said save backup/restores are handled from the big SD card (i.e. one that comes with the 3DS), so nice reading skills mang. I'm pretty sure you're just one of those people who can't afford the cartridge(s) and are pissed that you can't freeload off of other peoples' work via a free solution.never being forthcoming with the save backup/restore details
Oh yeah, say they suck when no other 'team' has come close to even this amount of progress. Go ahead and do it yourself if you think you could possibly do it so easily.

I assume it's just in RAM (like the PSP stuff was for a while), so it's lost after a shutdown, and thus the patch fixing the original hole stops it from being used anymore (since it can't be launched in RAM).
And I'm going to be honest: Do not expect it to work. If you want a Gateway, buy an older 3DS. The "we'll get it working" is the same BS we've seen from flash cart teams for years. The big exploit was killed in 5.x, we've known that for ages. Another one that functions the same has not popped up yet (which is why the 3dbrew wiki urges devs to stay on 4.x).
So the number of people who can actually use it is rather limited.
