The framwork question

   Through reading the ProgramGuide doc and the type lib, 
I got to know that all the main Interfaces in 'TE pro'
were  realized by TerraExplorer com class ,
all we need to do is to query other interface from
ITerraExplore.
Though there are some other com classes in the ocx control,
like:'TE3DWindow','TENavigationMap','TEInfomation','SkylineProtocol',
'NestedDispatch' and so on
(I thought the Interface of these com classes were reused by TerraExplorer 
using 'contain' or 'Aggregation')
but don't you think that the TerraExplorer  com class is too big to maintain?
Why don't use 'composition' style,like MapObjects(the product of ESRI).
All the components in MapObjects are independent,but through 'composition',they 
can work together perfectly,and much easier to maintain.
