With the amount of margins that have been tweaked for RTL, I don't know why you don't just create a SCSS mixin

[C-Lodder]

Something I've quickly mocked up if you are interested.

Mixin:

@mixin margin($position, $size) {
  margin-#{$position}: $size;
  
  $rtl-position: null;
  @if $position == 'left' {
    $rtl-position: right;
  } @else if $position == 'right' {
    $rtl-position: left;
  }

  @if $rtl-position != null {
    [dir=rtl] & {
      margin-#{$rtl-position}: $size;
    }
  }
}

Random element class:

.myClass {
  display: block;
  @include margin('left', 2rem);
}

This will add your desired RTL code and ignore top and bottom

@C-Lodder
Sorry, but this kind of code is above my skills.
I can close this if you like and let you propose a new PR.
