LogicException: The hook update_dependencies does not support attributes

Problem/Motivation

Running a PHPUnit test with webform at the latest core dev 11.x, we get a logic error and the test halts with the following:

LogicException: The hook update_dependencies on class Drupal\webform\Hook\WebformInstallUpdateHooks does not support attributes and must remain procedural.

Here is an example phpunit job from Gitlab Templates Downstream, the project used to test changes to the the contrib Gitlab Templates → . The error is caused only by requiring webform in the project's composer.json. It is not actually being enabled or used in the tests.

This is not an urgent problem, as Core 11.3.0 is not planned for release until December 2025, according to the current release cycle → , but I am raising this now, at the point when I found it, just so that it is recorded.
