OK, that might be true, but lets look the actually encoded parts:

Python 2.3.2 (#1, Oct 11 2003, 11:13:40) 
[GCC 2.96 20000731 (Red Hat Linux 7.3 2.96-113)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import mimify
>>> mimify.mime_encode_header('This is an ascii only header')
'This is an ascii only header'
>>> from email.Header import Header
>>> Header('This is an ascii only header', 'iso-8859-1').encode()
'=?iso-8859-1?q?This_is_an_ascii_only_header?='

Encoding that is unnecessary. It is harder to read that as raw without
decoding.

It will cause problems in programs that do something automatically,
but do not decode it. A good example is filtering that is done based
on subject prefixes.
