We need to investigate how to safely remove the `guzzle_cache` dependency from the `EclipsefdnClient` class in the `eclipsefdn` module. The `guzzle_cache` contrib module is currently not compatible with Drupal 11. Although it is still possible to bypass this incompatibility and it does not block upgrading our sites to Drupal 11, relying on this workaround is not ideal long-term. As part of this investigation, we should evaluate whether Drupal core’s caching mechanisms can replace the current usage of `guzzle_cache` and meet our existing requirements. **Goals:** * Assess how `guzzle_cache` is currently used in `EclipsefdnClient` * Determine if Drupal core caching APIs can provide equivalent functionality * Identify any gaps or required adjustments * Propose a path to safely remove the dependency
