@civodul I think a good improvement to Guile's issues could be to motivate more Guix developers to take part on Guile (I'll put the ML on fire again with some essay about why we should pay Guile more attention).
I think many people, and now I'm talking more in general, are afraid to take part in the development and the maintenance of a programming language, probably because the covers of the books that explain them have a very scary dragon.
But this we need to improve.
