Yes, this all sounds nice, but not good enough if you put yourself in my 
shoes when I suggest my user:

A. "I am going to install CentOS which is binary replica of RedHat 
Enterprise", so whatever works on RedHat Enterprise will work on CentOS 
[implying my reputation behind merely an ability to install binary 
packages and common sense of what binary files are there on both systems 
in questions]

B. There is CentOS which is promised (I am borrowing your phrasing here) 
"WILL BE extreamly similar to RHEL + a couple months"

but in the second  case I can not put my reputation at stake and finish 
my phrase with "whatever works on RedHat Enterprise will work on CentOS".

So my latest phrasing to my users/machine owners - which I can put my 
reputation behind - is:

I am going to install Debian for you, and as in the past whatever works 
on some Linux I should be able to make work on your Debian machine.

The last I can put my reputation behind, and my user knows it might not 
be as simple as installing binary packages known to work on RedHat 
Enterprise, and knows there will be some effort/time on my side involved.

My apologies for breaking my promise to stop pondering the issue ;-(
