... i'm aware, thus the leading dots. as i saw no suggestions in your
message -- just a statement -- i chose to provide some 'hopefully'
constructive comments rather than make assumption on what you were
hinting at. obviously, no one is able to foresee the existence of a
project built internally within another company let alone the api of
said project, i'm not sure what the proposed resolution is.
as the scope is different between ekko and freezer (same for monasca and
telemetry according to governance voting) what is the issue with
having overlaps? bringing in CADF, if you define your taxonomy
correctly, sharing a common base is fine as long as there exists enough
granularity in how you define your resources that differentiates a
'freezer' resource and an 'ekko' resource. that said, if they are truly
the same, then you should probably be debating why you have two of the
same thing instead of api.
