Will UDF (User-Defined Functions) as done up to FB 2.5 (based on DLL or SO libraries) on Firebird 3 be considered obsolete or even disappear in future versions since the new features of SQL functions, sub-routines and packages?

How will work the external functions, procedures and triggers in C, C++, Pascal and Java? They work similar to FB 2.5 UDFs (DLL / SO libraries)?
