Comment(by singingwolfboy@…):

 Thank you for taking up Haskell maintainership! I believe I've dropped
 maintainership on any Haskell ports that I used to maintain, but if you
 come across any that I've missed, I officially give you permission to
 remove me from the maintainership list and add yourself instead.
