do people really complain about significant whitespace?

Exactly.

Here is fragment of my python-mode.el:

"""
The \\[indent-for-tab-command] and \\[py-newline-and-indent] keys try
to suggest plausible indentation, based on
the indentation of preceding statements.  E.g., assuming
py-indent-offset is 4, after you enter
\tif a > 0: \\[py-newline-and-indent]
the cursor will be moved to the position of the `_' (_ is not a
character in the file, it's just used here to indicate the location of
the cursor):
\tif a > 0:
\t    _
If you then enter `c = d' \\[py-newline-and-indent], the cursor will
move
to
\tif a > 0:
\t    c = d
\t    _
Python-mode cannot know whether that's what you intended, or whether
\tif a > 0:
\t    c = d
\t_
was your intent.  In general, Python-mode either reproduces the
indentation of the (closest code or indenting-comment) preceding
statement, or adds an extra py-indent-offset blanks if the preceding
statement has `:' as its last significant (non-whitespace and non-
comment) character.  If the suggested indentation is too much, use
\\[py-electric-backspace] to reduce it.
