Not at all. The issues described in the linked post have arisen _because_ the community has grown so much and so fast over the past few years.
Yes, it has grown, and now it is going flat. Try to visualize the trend - imagine a bell curve (the only type of curve hackers know) and point out where the current time stamp is - on a growing or falling slope? ^_^
OK, to look a little bit more professional: doing a major rewrite of already mature project is a tricky thing (look what a terrible mess Gnome3 is or a recent Ubuntu), because users are passive and tend to use what they call a stable versions.
We can see the same situation with Python3 (although it has real improvements and much less buggy) and with ruby19, where the Rails guys are pushing it as hard as they can, but inert users still want 1.8.
So, users are happy with drupal6 and variety of third-party modules, while independent developers are losing their interest.
Clearly shows both Drupal 7 usage (and consequently Drupal usage as a whole) continuing to increase at a steady, fast rate.

To put this into perspective, Debian once had a Webmin package in the distant past (about 10 years ago)...at a time when we had far less than a million new downloads per year (might have even been in the low hundreds of thousands). We're currently at about 3 million new downloads a year, and growing every year, and there is no Ubuntu or Fedora package for Webmin.
All you can assert based on a lack of packages in the standard OS repo is that there is a lack of packages in the standard OS repo.
