I want to understand why the DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES is true for default

[farsunset]

Why ?
Why ?
Why ?

Usually we hope to igonre unkown properties when deseriallzation a json to java bean,
But your forget disable FAIL_ON_UNKNOWN_PROPERTIES ,this is a big bug , i think!
When in the prod mode , the bean remove proterties , no one hope has fail , but your get crash~

@farsunset This is NOT A FUCKING THING TO REPORT ON ISSUE TRACKER!!!!!!

Especially impressive that there is template saying this is kind of thing not to create issue for.
But the issue itself would be for different repo, where there is actually an issue suggesting change in defaults:

FasterXML/jackson-databind#493
