Comment:

 > The plugin is not calling `load_textdomain()` early. Instead, its
 textdomain is being auto-registered early by `wp-settings.php` based on
 the plugin file's "Text Domain" tag

 > Can you explain what's going on here and detail the new implications and
 requirements for plugins? It seems like the plugins are being called out
 for textdomain loading they're not responsible for.

 This `_doing_it_wrong` notice is not about calling `load_textdomain()`
 specifically. It's about triggering ''translation loading'', for example
 by calling `__()`, too early.

 While this message was already introduced in 6.7, there were some edge
 cases where it didn't fire. In 6.8 that's not the case anymore thanks to
 that `wp-settings.php` change.

 > Is this an intentional move to flush out the mistimed plugin translation
 calls?

 Yes. Again, see https://make.wordpress.org/core/2024/10/21/i18n-
 improvements-6-7/ and https://make.wordpress.org/core/2025/03/12/i18n-
 improvements-6-8/. They contain some good examples and explanation why
 loading translations too early is bad.

 If you have a plugin doing it wrong in the repo or on GitHub, I am happy
 to take a look and point out why it might happen in your case.

 You're definitely not expected to do things like `did_action( 'init' )` in
 your code à la https://github.com/pods-
 framework/pods/pull/7398/commits/7b93ffdb353183f3713cf3fc9751deb13f8d6cdc.
 That could just make things worse by unintentionally removing any user-
 facing texts. Instead you should figure out why your whole code is loaded
 too early and what you can do to avoid that.

 PS. There is no reason to reopen the ticket. Discussions can continue even
 on closed tickets. So let's do that please :)
