Agreed. There is no need to use a custom flavor of BEM.<p>You might be able to enforce a distinction between elements and modifiers (with elements nested below parents, while modifiers are siblings of the elements they modify) like so:<p><pre><code>  .accordion {
    .accordion-item { }
    .accordion-item-selected { }
  }
</code></pre>
But this requires nesting where true BEM otherwise avoids it.
