When configuring the entity_delete_log module at /admin/config/entity-delete-log, there is no option for "Node". The closest option is "Content". I can understand the frustration with Drupal core's inconsistent terminology, so I understand the desire to call nodes content. However, the machine name of the entity type is node not content. Terminology aside, the real problem is that in entity_delete_log_entity_delete() there is this bit of code:
// If the incoming entity type is enabled for logging, let's log it.
if (in_array($type, $entity_types, TRUE)) {
Here $entity_types is an array of each checkbox checked on the entity_delete_log configuration form, including "content" if checked. What this means is that when a node is deleted, the if statement evaluates to false and the node deletion is not logged.
Somehow fix this in a backwards compatible way.
I set the priority to major since node is by far the most common entity type.

Sorry, I created this too quickly. Apparently it was a side effect of updating entity_delete_log from a very old custom version to the latest version. Once I resaved the module configuration I see $entity_types contains "node" not "content". Closing!
