The 'modern' way is to use a local utility registered in a local

An advantage is that you don't have another tool in the zmi. But that
can also be a disavantage.
I think the consensus is now that the modern way you describe is wrong:
persistent utilities introduce a lot of problems. You can easily see
this if you add a persistent utility to your site and then remove the
package from your instance: suddenly your entire instance is broken.
My advise would be to store your configuration in portal_properties and
use a non-persistent utility.
That's good to know. It's hard to follow the state-of-the-art without a
canonical developers manual (but that may change).
Is there good example code that can be used as a reference?
Especially I'm interested in:
- the storage (Annotation, Propertysheet)
- formlib or z3c.form (what's will plone core go?)
- the way to bind the form code to the storage without much
boilerplate
I would update Maltes Howto (and eventually other Documentation) with
this best practice.
