1) From previous posts to this list folks have mentioned their 
organizations prohibit touching anything less then a GA or maybe a late 
RC. That comes from on high and I doubt the folks issuing the orders are 
on this list.

2) The attitude comes from lessons learned in the School of Hard Knocks. 
Until someone or someones can guarantee a new GA release will not eat 
your data or spring security leaks then the prudent thing to do is wait 
to see what happens when it hits the world at large. I learned this 
lesson, pitfalls of jumping into something new, across fields outside of 
software as well. In other words 'new and improved' is not always the 
case, see 737 MAX as case in point.

3) Progress happens and you need to keep up. A little caution is good 
thing though, especially if you are the one who is being held 
responsible for any adverse outcomes.
