in this example, you strictly define a new "my-mapping" packaging, like done in 
Maven core for every default packagings [1] with documentation in [2]: don't 
call it bindings, but simply "packaging-bindings.xml" and it's more clear

the more I think about it, the more I feel that what we need is 
pluginManagement and eventually plugins import, like we did in the past for 
dependencyManagement [3]

This would permit:
- to import plugins versions form an external source,
- share plugins configurations and executions either in the reactor, either 
from outside

I still don't know if this import should be triggered as a dependencyManagement 
scope, like "import" scope was added

Or if we could do something at dependencyManagement and/or dependency level.
Given "extensions" is a boolean represented as a String (for inheritance 
reasons), why not use this String to have support 
<extensions>import</extensions> that imports content?
