Performance issues on Edit Entity form with a lot of usages

Problem/Motivation

Any Edit form for an entity that has a lot of usages start to load slower, even causing the WSOD with 500 HTTP code.
Profiler log:

Steps to reproduce

1. Remove the listSources call
Remove the listSources call entirely from entity_usage_form_alter:

<?php
  $usage_data = \Drupal::service('entity_usage.usage')->listSources($entity);
  if (empty($usage_data)) {
    return;
  }
?>

Reasoning:
It makes little sense to load thousands of entities simply to conditionally display a warning message.
Given that this warning does not block editing or saving, it is impractical to force a wait time of 10–100+ seconds just to decide whether to show a message.
Additionally, the $usage_data variable is not utilized in the error message text or anywhere else in the function.

2. Updated Message Wording
a. Edit Warning:
Current: Modifications on this form will affect all existing usages of this entity.
Suggested: Modifications made here may affect all existing usages of this entity.
b. Deletion/Recorded Usages:
Current: There are recorded usages of this entity.
Suggested: There may be recorded usages of this entity. Please verify usage before proceeding with deletion.
