I'm sorry then, let me try to explain better...

> - if they should be promoted/demoted in their support level?
The list includes (1) HA packages and (2) HA related packages. This initial package list was informative only and supposed to get feedback about missing HA packages (like haproxy, for example) OR HA packages that should be fully supported (in [main]) instead.
In that sense I got feedback from @freyes and @sabdfl about keepalived being considered as "deprecated": Felipe told me there is a important dependency for openstack, Mark suggested me to check on the snap coming directly from upstream after he started an initial snap (I'll check this for 20.10).
For the other half of the e-mail.. it listed "so many things" because it listed "all resource agents" pacemaker supports (yes, it is a *lot*). And it is even more.. since it supports all "sysv services" and "systemd units" you have installed (but then agents are *generic*, without specialization for particular service, or supporting multiple instances).
In the resource agents list... I used some terms that are mostly used by support organization, specially to get feedback from them about this (I had CC Dan before).
What I had in mind was:
----
1) FULLY SUPPORTED - Pacemaker Resource Agents that depend on packages in [main]. The resource agents should be *fully supported* like the packages are: they are fully supported by Ubuntu Advantage & have higher importance to us in LP (server team is subscribed to all server seeded pkgs, for example).
2) BEST EFFORT SUPPORT - Pacemaker Resource Agents that depend on packages in [universe]. The resource agents should be supported as *best effort attempt* like the packages in [universe] are: They are supported as "best effort attempt" by Ubuntu Advantage & have less importance to LP (mostly driven by MOTU or specific bugs impacting too many people).
3) COMMUNITY SUPPORT - In this category I placed Pacemaker Resource Agents done by 3rd party for their specific products or solutions. We, as community, could forward any bug opened against these agents to upstream project and sync LP if needed... or even check if "resource-agents" upstream has a fix for it.. but it could be difficult to debug without upstream involvement.
4) UNSUPPORTED - Pacemaker Resource Agents done for products that aren't supported in Ubuntu Linux (Oracle, Sybase, SAP, ...)
5) DEPRECATED - Pacemaker Agents that are deprecated and should not be used.
----

I'm adapting "resource-agents" resource to its core package (or dependency) and not the opposite. Example: If resource agent was made for *squid* and *squid* is in [main], then I should consider the *squid resource agent* as being fully supported.

It only means that for the "HA related packages" I'll probably be helping to solve bugs because they are important to HA. But nothing to do with my original email intent, so you can skip that list.

I hope it was clarified now.

The *discourse* part was going to be a second phase in my head... to document whatever we have discussed here, but maybe my long e-mail scared people =).
If discourse is the way to go, then I think I prefer finishing up the HA documentation for 20.04 with all my pre-concepts and then do what you suggest: I don't think there will be much feedback either way.

Perfect.

Ok.
Thanks a lot for the careful review!
