I'm not following SCL in Fedora, but even the first way suggested by 
Toshio is against this basic premise. When you have another .spec file 
in extra branch, it's not the "very same .spec file" and I actually 
don't see any reason why SCL spec file should be buildable as non-SCL 
package (unless we decide to build them from "very same branch" - 
meaning that you would have single .spec file in "f19" branch and build 
it twice - once as SCL and once as normal package). I don't see use-case 
for this.

I agree it could be easier to maintain the packages this way, but for 
bigger packages like php it's just lot of extra conditionals which makes 
the maintenance harder.

If I'm right, this basic premise is SHOULD (not MUST) in current guidelines.
