We initialize models as part of the warmup process in production, so this was being logged on every boot. We only want to log if a plugin is actually using the model, so after_save is a safer bet.
Certain DBs have duplicates already, if we want to ensure uniqueness here
we need to decide first how to clean up existing data and confirm all the
plugins expect this.
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
