I didn't say Moose was "too complex" of itself, just that it was too complex to do any sort of justice with a brief overview (amongst several other brief overviews) within a typical conference session.
Personally, I think that Moose is far too complicated internally, and far too slow to risk holding it up as an example to Perl neophytes coming from compiled languages. They'll code up some simple hierarchal OO standard test--A genus tree or managerial hierarchy--run it twice and walk away. It even throws away the slim performance advantages that native Perl OO has over Ruby and Python.
Performance may not be eveerything, or even a significant something for many people, but exagerating and exacerbating the compiled/interpreted differences by using an OO framework that enacts such a penalty, in order to achieve functionality that very few will ever feel the need for, just doesn't make sense to me.
Class::MOP seems to see "Meta Object Protocol" as an end in itself, to the detriment of all other considerations. The docs do a good job of listing what it can do, but a pretty poor job of explaining why you would ever want to do those things.
As an exercise in exploring what and how Perl 6 might work--hopefully without the penalties--it is an incredible piece of work. As a useful and usable piece of Perl 5 everyday wear, I have my doubts. Maybe Mouse, I haven't gotten to try that recently to see how it is faring.

In the absence of evidence, opinion is indistinguishable from prejudice.
