However, currently existing TFPGList implementation would be unable to deal with refcounted objects correctly because TFPGLists uses TFPSList (u can examine source file if interested), and TFPSList moves items like memory blocks. So TFPGList can not store refcounted objects just like it can not store interface vars.

You are wrong. TFPGList works correctly with reference counted types, 
because it overrides the necessary functions of TFPSList (mainly 
CopyItem). Afterall TFPGList<AnsiString> works without problems ;)
