The thing is that Python programmers already know
how to deal with lists.  So if you tell them that the options
being parsed are just a list, then they can figure out how
to do 
	optionlist.append(foo)
for themselves rather than need to learn add_option.

And since the help message uses the same order as the list,
they can figure out how
	optionlist.insert(0, foo)
	optionlist.extend([foo,bar,baz])
etc. will work.  

If you stick to just add_option, you end up either
not having the expressiveness of the list operations
or having your own names for them.
