This y-release of Kafo requires that all puppet modules support Puppet 5?

[ekohl]

Correct - it verifies the OS is listed in metadata.json and the running puppet version matches the constraints. The current issue is that puppetlabs-mysql doesn't allow puppet-staging 3.0. We need puppetlabs/puppetlabs-mysql@c5eb9ba to be in a released version. I haven't checked how it handles modules without a puppet metadata version (https://github.com/jlambert121/jlambert121-trusted_ca/blob/master/metadata.json - used in Katello) but I'm leaning to forking that anyway (jlambert121/jlambert121-trusted_ca#37).

I don't think that's a fair summary. Kafo 2.1 added a feature to parse module metadata and validate the module can be used by the puppet that's used. There's a --skip-puppet-version-check for disabling it. See this for more details theforeman/kafo#213 in fact it let us know about possible incompatibilities that we ignored so far.
