Version tags should be used for questions that apply to a version only, not to merely say what version a site is using.

Jan 14, 2023 at 10:45 comment added 4uk4 This is not the only API change because of Symfony. I find the Symfony exception handling far more capable. Core provides HTML exception subscribers for 4xx exceptions and fall backs to plain text error messages in case of 5xx exceptions. It would be no problem to add a custom event subscribers (what the OP is trying to do) to catch 5xx exceptions and set an HTML response.

Jan 13, 2023 at 19:36 comment added 4uk4 This issue is about the Drupal 7 perspective on fatal errors. Catching an exception in an Symfony event subscriber is not a fatal error and you are in full control to set an HTML response instead of a plain-text message.
Jan 13, 2023 at 18:16 comment added Jaypan There was a method for this in D7, but it was broken between D7 and D8, and has still not been repaired. You can use the patch from this issue however: drupal.org/project/drupal/issues/2720109
