I think what really gets lost here is that just because a package is
rebuilt from the same package sources, it doesn't mean that it is
exactly 100% binary compatible. SL has stated that they maintain
compatibility but certainly do not guarantee it. By and large, most
packages probably are ABI identical and some may be slightly off but you
may never even notice it. However, if you ever did encounter cases
where there differences, that may cause major headaches for you.
The only way I could see the two projects 'merging' would be if the
CentOS goals remained and established the base OS and SL became the
addons and enhancements repo. Similar to the CentOS plus repo, ABI
compatibility may have to be broken by the SL additions but that would
be an end user choice.
I kind of thing that as others have mentioned already, keeping them
separate allows for more choice for the end user base. Some people
could care less about RHEL compatibility. Some may not care a helluva
lot but would prefer to have it lest they be bitten in the backside at
some point, and others demand it.
For those that demand it, sure purchasing RHEL would be a logical
option, but some people really do not need the support agreement. I
(certainly like many others on this list) have been running Linux boxes
for more years than I can count and I have never had to contact a vendor
for support. When I have had issues, I've been able to contact the
upstream package provider directly and have managed to get fantastic
support far beyond you would ever get from a commercial offering of any
