 As a wrapper around [`overrideAttrs`](#sec-pkg-overrideAttrs), `lib.extendMkDerivation` passes the whole set of arguments directly to the base build helper before extending them, making it incompatible with build helpers that only pass part of their input arguments down the base build helper.
 
-To workaround this issue, [`lib.customisation.adaptMkDerivation`](#function-library-lib.customisation.adaptMkDerivation) is introduced. Instead of taking an attribute overlay that returns a subset of attributes to update, it takes an argument set adapter that returns the whole set of arguments to pass to the base build helper, allowing the removal of some arguments. The expression change needed to adopt `lib.adaptMkDerivation` is also smaller, enabling a smooth transition toward fixed-point arguments.
