Totally - and that's a good point. I think we may just need to update 
the wording some. The intent has always been that we develop targetting 
the software we think is appropriate for OpenStack- but the LTS line and 
testing are to ensure we don't introduce a dependency that's 
unreasonably hard to backport on top of an LTS release.

An example of that would be growing a dependency on a kernel feature 
that would be too much to backport - or if we had decided to move to 
Python3 back in the RHEL6 days (before there was a python3 available)

RDO and UCA are both ways that the distro vendors themselves are 
providing backport software on top of their LTS releases. So if it's in 
one of those the distro vendor themselves have de-facto communicated 
that it's not unreasonable to backport that piece of software to run on 
top of the LTS - since they have already done it.

All of that is not spelled out clearly though - so I agree, it would be 
potentially useful to describe that situation more clearly in the PTI.
