UTL_ENCODE function request

How does one go about requesting functions be added to an Oracle Database Standard PL/SQL package?

I would like for these 2 functions to be added to the UTL_ENCODE package

FUNCTION BASE64URL_DECODE(

r IN RAW

)

RETURN RAW;

FUNCTION BASE64URL_ENCODE(

r IN RAW

)

RETURN RAW;

These would like UTL_ENCODE.BASE64_ENCODE/BASE64_DECODE but take the base64URL character set.

This is very helpful when dealing with HTTP related development.

FUNCTION encode_to_base64url_str

 (

  in_raw             IN      raw

 )

 RETURN                     varchar2

 AS

  v_rv                     varchar2(32767);

  v_base64_binary                raw(2000); -- 2000 bytes

  v_base64_str                 varchar2(32767);
