Just putting connection points on the end of lines might be relatively easy 
to code. But I'm not yet convinced the resulting behavior would be an 
improvement.
For example: what should happen if you move one of the line segments? The 
current behavior is Handles just give up the connection (try moving a line 
connecting two boxes either moving a handle or the whole line).
Connection points on the other hand are preserving their connections (try 
moving one of the boxes connected by the line).
Now with both ends of the line having both a connection point and a handle 
what is going to happen?

So to quote Linus Torvals: "Talk is cheap. Show me the code."

The question of Connection Points vs. Handles was discussed in great length 
before. Please see:

for some details.
