 Direct upgrades from Debian releases older than 6.0 (squeeze) are
 not supported. Please follow the instructions in the Release Notes
 for Debian 6.0 to upgrade to 6.0 first.

Thanks. I hadn't seen that. (And there's a typo: upgrade to version
7.0 first.)

What do you want to bet though that there'll be a lot of pushback
against this in the form of a long email flame war?

I doubt it. Most people running stable on a workstation will keep it up
to date, they won't upgrade after missing an entire release. Most people
running stable on a server are very keen on doing anything that will
reduce the chance of having to reinstall, with ten years' worth of
tweaks to add, and will follow the release notes to the letter.

There will only be a few who claim that jumping a release is a great
thing to do.

There's already been one thread about this on debian-devel@ and it was
a typical thread where the pro and con make their points but no
decision's reached. That discussion'll be back because there are
people who think that they ought to be able to go from squeeze-lts to
jessie in one step - and they'll tell you that one upgrade is safer
than two.

  based upon my recent attempt to jump versions
it's really much easier to back up your user data
and then reinstall.

  i ran into all sorts of chicken and egg problems
and didn't have the right bits locally to make
the transition (specifically there was a version
of tar that is used to unpack the debs and in
one case it could not understand the .xz format
and thus would not work in any fashion and to
get a version installed that would work meant
having to upgrade libc and that then dragged in
all sorts of things like multiarch)...  it was
much more involved than an initial install.
i really suspect that is the most direct answer
that applies from those who would be concerned
with making it work.

  if i'd had a more recent media download i
would have stopped after about a half hour of
attempts and just done that.  but it _was_ an
interesting exercise...

Two upgrades that are almost certain to work are safer than one which
hasn't been tested...

Anyone who has the slightest familiarity with Debian (including
developers?) will know that the order in which things are done can be
extremely important.

A system which has been upgraded from a previous release will not be
identical to a clean install. Functionally it should be the same,
but not in detail. And I've more than once been faced with a massive
logjam in a sid upgrade, where aptitude wanted to remove half the
system, and managed to manually complete the upgrade with no removals
with a bit of trial and error, selecting things to upgrade piecemeal.
These things suggest that skipping a release is a bad idea, and may
well leave you painted into an inaccessible corner.

Something a bit related that I do usually do is to install unstable with
a single dist-upgrade from stable to unstable. But unstable is usually
very similar to testing, and I only do this with a bare console-based
minimal installation, before building the system up in unstable. But
even then, I'm prepared to find a case one day when that won't work, and
I have to do it again in two steps. No problem, there's no real
investment there. There most certainly is a great deal of investment in
a production system, too much to risk to save an hour or two.

Feel free to join the flamewar when it takes place - because it will.

Actually it's not, you have to read the Release Notes for 6.0 to upgrade 
to it ;)
