If JuKa means, the (very) old Japanese sound, yep I would like it back also. But for the reasons posted by Chrono, I doubt it will come back.
Or it could be that JuKa doesn't mean the old version of the /snoexcuse sound, but the fact that /snoexcuse doesn't work anymore...
But in that case: the command is changed to /sdanger. (and this will hold the newer noexcuse sound)
For those who can't follow, read the thread pointed out by Chrono
