Yeah, the history of Telemetry is a bit unusual in how it developed, and
I could give editorials and opinions about decisions that were made and
how well they worked in the community, but I'll save that for another
time. I will say that communication with the community could have been
better. And while I think that simplifying Ceilometer was a good choice
at the time when the number of contributors was dwindling, I agree that
cutting out a feature that is being used by users is not how OpenStack
ought to operate. And now I'm starting to give opinions so I'll stop.
I will say that it may be beneficial to the Telemetry project if you can
write out your use case for the Telemetry stack and describe why you
want Events to be captured and how you will use them. Describe how they
important to your billing solution (*), and if you are matching the
event notifications up with other metering data. You can discuss with
the team in the meeting if that use case and set of requirements goes in
Storyboard or elsewhere.
(*) I am curious if you are using CloudKitty or another solution.

I'm really glad you recognize the benefits of contributing back to the
community. It gives me hope. :)

Developers leaving the community is a normal part of the lifecycle, so I
think you would agree that part of having a healthy project is ensuring
that when that happens the project can go on. Monasca has already seen
a number of developers come and go, and will continue on for the
foreseeable future. That is part of why we wrote a spec for the
events-listener, so that if needed the work could change hands and
continue with context. We try to plan and get cross-company agreement
in the community. Of course, there are priorities and trade-offs and
limits on developers, but Monasca and OpenStack seem to do a good job of
being 'open' about it.
