possible practical application?

What is a possible practical application?
Maybe some sort of unikernel haskell code deploy?
What are the special features of the hOS? Since haskell is a very special lang then I'd expect hOS is very special OS.

Software doesn't need to be useful. It can be done out of joy or curiosity.

sure
but I wonder if there is special outstanding haskell software given haskell is outstanding lang?
