Configuration shoule be allowed more information in case of FIX hosting server highly security

Dear all,
I'm implementing FIX.4.4 and trying with QuickFIX/J released version 1.0.3 but I found that It's not suitable with our need because there are only few parameters in configuration file.For example: SenderCompID, TargetCompID, SocketConnectHost, SocketConnectPort

Should we allow user to configure more paramteter to fit with their need ? Ex:
+ SenderSubID (Tag=50)
+ MessageType (Tag=35)
+ Username (Tag=553) that use for session logon message
+ Password (Tag=554) that use for session logon message
+ ...
Beside that should we open source code for package quickfix-jni.jar that allow user customize each of elements....to meet their requirements.

Thanks and best regards,

Quoc Nguyen.
