puppet-common 2.7.26 depends facter (<< 2.0)

[Brian Witt]

I noticed today that the puppet-common 2.7.26 deb package for Ubuntu precise at

https://apt.puppetlabs.com/pool/precise/main/p/puppet/puppet-common_2.7.26-1puppetlabs1_all.deb

depends facter (<< 2.0) even though the facter page
https://docs.puppetlabs.com/facter/
says

"The currently supported Facter versions are 2.x and 1.7. Both versions work with Puppet 3.x and 2.7."

I've manually installed facter 2.2.0 (via dpkg) and it seems to work fine with puppet 2.7.26, so I'm confused by the dependency. Why is that there?

Thanks,
Brian
