2.8.0 ignoring root-modules?

[sellout]

I’m on Weeder 2.8.0 (#176, NixOS/nixpkgs@134eef3) and it seems to be ignoring the root-modules setting.

I’m setting up Weeder on an existing project, so I started by adding everything that currently has issues to root-modules:

root-instances = [
    { class = '\.Bifoldable$' },
    { class = '\.Bifunctor$' },
    { class = '\.Bitraversable$' },
    { class = '\.Eq$' },
]
root-modules = [
    '^Unison\.Util\.BiMultimap$',
    '^Unison\.Util\.Logger$',
    '^Unison\.Util\.Relation$',
]
roots = [
    '^Main\.main$',
    '^Paths_.*',
]
type-class-roots = false
unused-types = true

The other fields all work as expected, and the syntax I used for root-modules matches test/Spec/ModuleRoot.toml, so I’m not sure what I’m doing wrong.

Also, I’m curious why the defaults add ^'Paths_.*' to roots instead of to root-modules. I imagine the effect should be the same either way?
