 Well the maintainers of llvm do, and that's who I'll trust:

     Trunk is now 3.7.0svn

     git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@226004

 notes),

 Yes, because those are beta as well.

 No, it's not analogous because the type of ports are different in those
 cases.  In the py26-numpy case, something is providing a module for use by
 clients of different versions of perl, python, ruby, etc.  In those cases,
 the *numpy* code is exactly the same, it's just built and installed for
 use by a different version of python.

 In this case, the different llvm ports *are* different versions of llvm.
 This is analogous to why we have multiple python ports or multiple gcc
 ports, etc.

 Clients of llvm can have variants to let users choose which version of
 llvm they want to use.

 Clients of python (or the py-numpy module) similarly can have variants to
 let users choose which version of python (and thus py-numpy) they wish to
 use.

 Yes.  cctools is the one that has the variant.  'port info' will tell you
 about a port's variants.
