My conception of its input was wrong. It is quite a useful construct, even if its name is a bit weird.

Attributes to add to the returned derivations,

which are not necessarily part of the build.

This is a bit like doing `drv // { myAttr = true; }` (which would be lost by `overrideAttrs`).
|
|
It does not change the actual derivation, but adds the attribute nonetheless, so that

consumers of what would be `drv` have more information.
