Yup I hope nothing I said implied a lack of comittment from the tripleo
team. If I understand the context of the 'minor update' work once it's
done you'll be ahead of the curve ;P

You're all welcome. This community is good at trying to see problems
from all sides and acting with maturity :)

Yup, as I said on the review I think removing the tag is the right thing
to do right now.

Yup, though to level set this wont be an immediate action. I'd like to
have a draft available before the Sydney summit

+1, as always let me know what I can do to help with this.
