Add back Zebra counting of nodes

Problem/Motivation

In D7 there was a hook counter for zebra variable.

function template_preprocess(&$variables, $hook) {
  global $user;
  static $count = array();

  // Track run count for each hook to provide zebra striping. See
  // "template_preprocess_block()" which provides the same feature specific to
  // blocks.
  $count[$hook] = isset($count[$hook]) && is_int($count[$hook]) ? $count[$hook] : 1;
  $variables['zebra'] = ($count[$hook] % 2) ? 'odd' : 'even';

This has been removed in D10 for unknown reasons. I need the add/even value in node.html.twig and I have no idea how I could re-implement this. Can someone share an idea why it was removed and if we could add this back?

Currently the node template does not know if it is the odd or even one.

The way to investigate changes is as follows:

Check out a Git working copy of Drupal.

Search the commit contents for the removal: git log -S'zebra striping'

The most recent commit mentioning those words is:

commit 9f723a46933159b41771f396b71c11156192c3c0 Author: webchick <webchick@24967.no-reply.drupal.org> Date: Mon Apr 15 08:21:21 2013 -0700 Issue #1968322 by effulgentsia: Remove unused $id and $zebra variables from templates.

Read over #1968322: Remove unused $id and $zebra variables from templates → to understand the reasons and note the affiliated change record, Zebra striping variables removed from templates → .

So this is an intentional change with suggestions of a modern replacement.

The issue summary needs updating to explain why putting this back into Drupal is needed.

In my specific example it is not about a CSS class only. I have a content type that need to change the HTML code.

Lets say

HTML Layout A for item number 1,3,5,7

HTML Layout B for item number 2,3,6,8

There is no theme suggestion, no class, no zebra and I have no idea how to solve this now...

The changes are somehow massive, so I cannot use CSS only to implement the layout changes.
