I could imagine that the theory could be quite helpful for accepting
nagging limitations.  I'm not an experienced Haskell programmer,
though, but that's what I noticed when using other languages.

I think it entirely depends on the amount of work you're willing to
put into it.  I couldn't bring myself to do it (my copy is mostly
unread), but it still helped me to figure out enough of the notation
in an emergency.  My take on formalization is somewhat unusual
anyway---I view it as a necessary evil to ensure intersubjective
verifiability, but if you need it to get any results whatsoever, you
either don't understand what you're doing, or it's not worth doing in
the first place because you're restating trivialities in a pompous
