Issue Description

The Avoid Naming Collisions section of the Best Practices page in the Plugin developer handbook includes the options to use prefixes, and classes, but not namespaces, to avoid naming collisions.

We do have a section on using namespaces in our coding standards, so it makes sense to add this to our plugin developer handbook as well.

Section of Page with the issue

The section Avoid Naming Collisions

Why is this a problem?

It doesn't include namespaces as a solution

Suggested Fix

Add a section on the use of namespaces as an option, after the prefix section. Include details on how to create good namespaces based on the WordPress coding standards
