This is what Delphi allows since long - except for the parent window 
restriction. The MDI menu is not a requirement to make an application 
MDI - it also is somewhat useless in a "virtual desktop", populated also 
with other (non-document) windows.

This clearly makes the IDE MDI - multiple document views managed by a 
single application, controlled by a single menu. An SDI application 
requires to start a new instance for every document view/window.
