As far as the CGL Spec or POC tracking list, my understanding is that it's okay to leave projects, such as Linux-HA, that don't implement the full requirement as references. In the POC tracking list, the "gap analysis" column is used to define which projects will/won't implement the full requirement.

Something that has been occuring to me in recent flurry of project
analysis to fulfill CGL requirements is that the projects and/or people
involved are not contacted at all to determine whether or not they may or
may not meet your requirements in the future.
You're simply speculating on the viability of these projects to meet your
needs, unless they explicitly state that they fulfill the requirements. As
was already seen with the 'Persistant Device Naming' (or whatever it is
called this week) Requirement, the collective speculation overlooked the
potential of the udev (and related) projects.
I fear that other speculation may lead to overlooking of other projects,
which will potentially lead to someone wasting a lot of time reinventing
something rather than reusing and improving something else.
The current practice is not very community-oriented. Although the CGL
project has not had a great reception in the past, it is imperative that
you communicate with the other Open Source projects you're evaluating
You guys are (still) the new kids at school. No one is going to come
running over to be your friends; you have to talk to the other kids and
make yourselves likeable. :)
