As Hrvoje has pointed out, 'sys' is part of the internal interpreter
machinery - it's there as soon as the interpreter starts. The import
call for it just grabs it out of the module cache and creates a
reference to it in the current namespace.
I understand that, but
Explicit is better than implicit.

sys.modules[modname]
Simple is better than complex.
--> three lines for a common use case instead of one
Readability counts.
--> why is sys imported in this WSGI app (that shouldn't generally
touch any of the common sys.argv, sys.stdout etc)?!
(500 lines later) aha, to access sys.modules
There should be one-- and preferably only one --obvious way to do it.
--> should I use the 3-line idiom? should I use the getattr() idiom?
Ideally, __import__() should support the only obvious way.
In short, the three-line version doesn't convey the intent in an obvious way
and does more work than is necessary.
