That's not what I am talking about.

I am referring to people who are wanting to work on/develope on new SW 
on 5 year old designs (CentOS5) or older CentOS4.

This kind of undertaking is non-reasonable and non-sensical.

Spear-head development/the bleeding edge needs to take place in a 
rolling release model, until "the development is finished".

When it's "finished", it's reasonable to switch to freeze the 
environment on what's current then.

Don't try to generalize your limited views.
