Review comment:
Putting a note here so that we don't forget. The SQL standard forbids all kind of explicit casts from DATE, TIME, DATETIME to non char datatypes and does not mention anything about implicit casts.

> The majority of strict type checks can be controlled by {{hive.strict.checks.type.safety}} property. HIVE-24157 introduced another property, namely {{hive.strict.timestamp.conversion}}, to control the implicit comparisons between numerics and timestamps.
> The name and description of {{hive.strict.checks.type.safety}} imply that the property covers all strict checks so having others for specific cases appears confusing and can easily lead to unexpected behavior.
> The goal of this issue is to unify those properties to facilitate configuration and improve code reuse.
