Yes, and lots of real-world situations that they faced during the development. 
That's what I meant.

Please read section 5 in the paper.

I am very sure they are aware of them. Interactive interpreters are simply not 
enough of a tool for commercial development - more sophisticated tools are 
necessary. In Haskell we don't even have basic things like code structure 
visualisation, efficient browsing and fully language-aware editor with typing 
support etc.
This is one of the ways of distinguishing the mainstream languages. Mainstream 
means that enough people use them for someone to put in the effort to build 
the tools.
