Irony in the Artistic license?

[John Lacey]

[I tried posting this to comp.lang.perl.moderated but it
disappeared into the ether, neither rejected or posted.]

The Artistic license says "[T]he Copyright Holder maintains some
semblance of artistic control over the development of the package
[...]", but then item 2 says "You may apply [...] modifications
derived from the Public Domain [...]. A Package modified in such
a way shall still be considered the Standard Version."

    http://www.perl.com/pub/language/misc/Artistic.html

I read this as saying that any modifications placed in the public
domain do not alter the Standard Version, and therefore a Package
with such modifications may be distributed as if it were the
original, with no notification to the Copyright Holder or the
recipients.

Is this an intentional loophole? Am I missing something? The use
of "semblence" seems troubling and indicative.
