because config transitions between packages are only tested on a
per-release base ... 
if the naming of config option A changed from "name" to "newname" that
will only be handled between two releases, if you skip the release where
it was handled you might lose the former setting. 
given that a default ubuntu install consists of 1000s of packages its
very likely you will lose configurations or end up with broken stuff
(even if you might not note it immediately)

several 100 people do update testing for several months every release to
make sure nothing is lost and your updates work reliably.
your way simply skips that QA effort and will result in unpredictable
system and user settings ...

if you really blog about it, make sure to put a big red warning around
that post to make sure "jane average user" knows that it might result in
breakage and is a matter of luck if it works.
