I completely agree with all of the above. 

I have written not-trivial (well, for me at least :P) libraries following this
mechanism and never ever had an issue with it. I agree that modules should not
pollute the global "namespace".

What is done is perfectly clear to everybody (newbies and seasoned developers
alike) and requires 1 extra single line versus the module approach. If a global
entry is wanted it's also very easy to add it as well from user side.
