It wasn't an April Fools' joke, it was a cacophony of random levels made by several people that couldn't possibly have been allowed on the forums on any other day than April Fools'. Several dozen versions existed and were distributed around prior to the topic being made.
I still think it was a pretty good wad and Boinciel did a good job, but it's not an absolute necessity to have a constantly updated version around all the time. Down the line we'll just dig it up if we feel like playing it again, just like we did with Penopat's 1.09 wads.
