ECK_ENTITY_ID_MAX_LENGTH

Problem/Motivation

When trying to migrate eck entities from Drupal 7 to Drupal 9, I get the error message "Entity id has more than 27 characters."
Unfortunately in Drupal 7 the length could be up to 32 chars and there exist entities with id-length of 32 chars.

Proposed resolution

Would it be sufficient to set the ECK_ENTITY_ID_MAX_LENGTH back to 32 or does that have critical side effects?
