Some theory in favor of adding a qualifier such as Alpha[n], Beta[n],
CR[n] and Final : https://developer.jboss.org/wiki/JBossProjectVersioning

Please do not commit your own changes to the parent.

Do not do that. Introducing SNAPSHOT dependencies makes builds 
irreproducible and unreliable. You never know which revision you get 
from the SNAPSHOTs repo. Looking at today's #hawkular logs, at least 
mazz, mtho11 and stefan_n know what I am speaking about.

It would be quite hard to find the criteria for deciding when to 
increase major, minor or micro in parent.
As far as the parent contained just maven plugins, there was no 
backwards compatibility in game. I admit it is quite different now that 
we manage dependencies there. But I see no way how semantic versioning 
could work with the parent either.
