Funny you should mention that... there is actually a related reason why I looked into these Bubsy maps... 
You're quite spot on. You know, I could think that collection would've had the often regarded entry from the Atari Jaguar, "Fractured Furry Tales", but, right now, it doesn't. I felt a bit awful it didn't sell many copies, and, well, not many people heard of it and didn't got much attention until quite lately. That game had some good speedrun videos some people made.
I never actually played that game myself, because, I never got the chance to. Looked like a good game, aside from the changes and improvements from "Bubsy II" not seen there. Read that game's source code was brought from the Genesis version and ported there before adding in new enemies, levels, and so on.
If FFT had a chance of being ported into the collection, I hope it'd be during development or in a patch later on. I'd be all over doing that game to see how challenging it was. If only someone could take the time to do it someday.
If anything, from my perspective, Bubsy FFT could've had an actual boss theme for each boss, and one more level having an actual final boss at the end, the true main villain responsible for twisting the fairy tales to his or her liking and messing up children's stories, which Bubsy could defeat and truly save them all.
To let you know, I spotted only one map about the game at AtariAge Forums posted by the game's programmer, Andrew Seed, no joke, but that map's a bit too small to see, 'cause the size was made smaller instead of full size to adhere to image size limits there. It's only the 2nd level of the 4th world, Waterbubsy, "Bubble Trouble", incorrectly labelled as "Bubsy 4C". Should've been "Bubsy 4B". No other maps have been made nor seen since.

https://forums.atariage.com/gallery/album/1847-bubsy-maps/There's a video interview I've found on YouTube about FFT's process conducted by Doctorclu with the game's producer, Faran Thomason. Doctorclu also did many speedrun videos about FFT. You should see some of 'em. That guy really did good, aside from some blunders trying to finish faster.
He also said in his recent forum post there, "Since that time, great efforts have been made for mapping Bubsy FFT, and people have been playing, so I'm sure that will change soon. Good to see FFT getting some love.". Sounds like he wants that game mapped to give that game more attention to the people. Would really help plenty of Bubsy fans having trouble with it. Really.
I only found that post lately while looking and felt that should be brought to your attention.
