I’d like to confirm that this issue is still relevant in Drupal 10.3.14.

When the google_tag_gtm_iframe theme hook is not implemented in the active theme, Drupal logs a warning:

The theme hook google_tag_gtm_iframe was not found.

While it doesn't break functionality, it pollutes the logs unnecessarily and causes confusion in production environments.

Making the

block optional via a setting in the admin UI (as this patch provides) would be very helpful — especially for sites using Consent Management Platforms (CMPs) that need to block all tracking methods, including fallback iframes. Thank you to everyone working on this — the patch and MR are much appreciated. Looking forward to this being included in a stable release!
