SqlBulkCopy: value boxed always?

[weifenluo]

From source code:

SqlClient/src/Microsoft.Data.SqlClient/src/Microsoft/Data/SqlClient/SqlBulkCopy.cs

Line 2252 in 1c0f397

object value = GetValueFromSourceRow(col, out isSqlType, out isDataFeed, out isNull); //this will return Task/null in future: as rTask

Does that mean every value read and write by SqlBulkCopy will always be boxed? I will need to implement a custom IDataReader for SqlBulkCopy, will SqlBulkCopy respect the strongly typed GetInt16/GetInt32/... implementation?
