Inconsistent data type support for jsonPredicateHints

[LazyRen]

Hello,

according to the protocol documentation: primitive types,
Delta Sharing supports 12 types of primitive type.

short | 2-byte signed integer numbers. Range: -32768 to 32767
byte | 1-byte signed integer number. Range: -128 to 127
binary | A sequence of binary data
decimal

However, jsonPredicateHints only support 8 types. Execluding short, byte, binary, decimal types.

Does this mean we cannot use 4 types for the predicate hints? I'm mostly curious on the short type. Can I use int to replace this?
