Is there any news about it?

No news yet, I guess.
If anyone's managed a workaround, please share!

I wound up just solving this by overriding the default analytics stuff in the theme. I did so by commenting out the google_analytics config in _config.yml and then making my own head file called includes/my-head.html (which Hydejack includes by default). The contents of that file is (be sure to replace <your GA ID> with your GA4 ID):

<!-- Google tag (gtag.js) -->
<script async src="https://www.googletagmanager.com/gtag/js?id=<your GA id>"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', '<your GA ID>');
</script>
