I agree, and think that a heading where the main content of the page
starts is more effective than a skip navigation link.  In fact, my
experience with SkipNav links has had surprisingly mixed results --
whether with a different screen reader, different version of the same
screen reader, or an apparently different HTML coding technique that
another web site uses.  It works as intended sometimes, but other times
does not skip ahead, or even worse, reloads the virtual buffer of the
screen reader, returning focus to the top.

1) When using a screenreader I can jump up and down a well constructed
page quite easily by going to the next or previous heading. If the
headings are not nested properly I start to wonder if I have missed
something and have to go into virtual focus to read all the surrounding
text. So for me "should" is a pretty imperative should.
2) Guidelines are just that - guidelines. If you have a very good reason
not to nest headings properly, and can at the same time ensure that the
reading sequence is logical, then fair enough. But I would love to see
an example of where this has been achieved.

This is desirable, but not required. If you look at the How To Meet
information for SC 2.4.10 (2.4.10 Section Headings: Section headings are
used to organize the content. (Level AAA)) you'll see the note below:

section headings. Other technologies use other techniques for
identifying headers. To facilitate navigation and understanding of
overall document structure, authors should use headings that are
properly nested (e.g., h1 followed by h2, h2 followed by h2 or h3, h3 f
followed by h3 or h4, etc.)."
