certbot will switch to Python 3 sometime in the future. If we want to ship the same version in EPEL 7 we need to provide a Python 3 version of python-acme (and thus python-pyrfc3339).
Would you mind making myself a co-maintainer for this package? I hope that my record of work for the certbot packages should be good enough so I can just continue fixing stuff without waiting too long.
