Is there a reason for using the class name rather than the tablename for caching guardableColumns?

if (! isset(static::$guardableColumns[get_class($this)])) {

The reason I ask is that in one of our packages we use a generic model class which sets the table name on instantiation. This means that when we load up the same model with a different table which may have different columns. The guardable columns will have cached the result from the previous model even though we are now using a different table.

Granted this might be unusual way to use a model but I was wondering if it made sense to use the table name instead for caching. Might also need to include the connection name to as well ....
