Some of Button vars seems not to be used

[Agile-fox]

Hey, I'm trying to make a theme for carbon but I started to face some issues as long as I want to modify something else then colors. In my case I wanted to modify button paddings and font weight.

I found that in @carbon\styles\scss\components\button\_vars.scss
We have those variables and few more:

/// @type Number
/// @access public
/// @group button
$button-font-weight: 400 !default;

/// @type Value
/// @access public
/// @group button
$button-padding: calc(0.875rem - 3px) calc(#{$spacing-10} - 1px)
  calc(0.875rem - 3px) calc(#{$spacing-05} - 1px) !default;

I have checked with my VSC Search and manually all of the button related files like:

• button.scss,
• index.scss,
• mixins.scss,
• tokens.scss.

And i couldn't find any part of the code referring to those variables declared in that _vars.scss file.

I tried using them and the one I mention above are not getting any effect on my component, for example $button-border-radius works but this one is being used in mixins.scss so it makes sense that makes an effect. So i have 2 questions.

1. those are some code leftovers / something not implemented yet or they have some purpose I'm missing?
2. Is there way to modify button paddings without affecting overall $spacing global tokens?

@use '@carbon/styles/scss/components/button/vars'  with (
    $button-padding-sm: 4rem,
    $button-border-radius: 16px,
    $button-padding: 8rem,
    $button-font-weight: 700 ,
    );
