I'm not an insider, but that sounds right to me.

I've mentioned this before, I think. The issue was one of
sponsor****p. There are Apple engineers who contribute (on their own
time) to RubyCocoa and PyObjC. Those engineers stepped forward when
management asked who would be willing to sponsor a "foreign"
development language, quality-check external contributions and
integrate them into Apple's internal build system, etc.
A sponsor did come forward for Perl, shortly after my rant a few
months ago. But my life (both personal and professional) has been
rather hectic since, and I wasn't able to deliver the goods in time
to ****p with Leopard. Mea culpa.

Installing a newer Perl hasn't been a problem for a long time - since
Jaguar. The problem back then was that the newer version - at the
time, 5.8.0 - tried to install its core modules under /Library/Perl
by default, mixing them up with any CPAN modules for 5.6 that had
been installed in the same location.
That problem was fixed, in two ways. First, as of 5.8.1, Perl
reverted back to using the traditional /usr/local for its default
install prefix. And second, Apple added version-specific
subdirectories, so even if one were to use a prefix of /usr to
install 5.10, its core modules still wouldn't overwrite any of 5.8.8's.
The best thing Apple could do is remove the old article about
upgrading Jaguar to 5.8. It was written before 5.8.1 was released,
and reflects the /Library/Perl default location of 5.8.0. It's really
no longer applicable. But, it's still the first article that comes up
at apple.com when you google for "macintosh upgrade perl", so a lot
of people still follow its advice, thinking that something at
apple.com is authoritative. At the very least, Apple should add "this
article is obsolete" in big bold red letters at the top of the page.

If by "discuss" you mean "strongly discourage", I agree with you.
