Additional python34 components for epel7

Hello there, To package some python3-based stuff I need 'msgpack', 'llfuse', 'Cython' modules built for Python 3.4 which is the current version of Python 3 in epel7. Would it be reasonable to file a bug against 'python-msgpack', et al. in epel7 to adapt the package spec and get 'python34-msgpack' etc. packages, or there are any objections against that? Thanks, -- wbr, Denis.
