Meta Best Practices Questions

What is the best practice for creating a class that exports some sugar and
extends the metaclass?  I generally like to use Traits/Rolls to extend the
metaclass, but I noticed the following comment in *
Moose::Cookbook::Meta::Recipe5:

*The disadvantage is that it's not easy to combine a trait with some sort of
sugar (like our notional has_table sugar).

Am I to infer this correctly, that it recommended that if you wish to extend
the metaclass and add sugar.   You should follow *
Moose::Cookbook::Meta::Recipe4* and:

extends 'Moose::Meta::Class';

Rather than use traits?

Thanks in Advance,
