If we start adding new properties, directives, keywords etc on every such request, the end result 
will deserve only placing into trash.
TComponent already allows
a) Using Tag property to store indices into array or other container of data of any type;
b) Using Components property to store any number of child components, which are owned, named, can 
notify and be notified of insertion and deletion.

Regarding the Tag type, the fact we're tied up with that "Delphi compatibility" is quite 
unfortunate. I wonder how they are going to maintain compatibility between 32 and 64 bit versions.
