I'm earnestly probing to try to get a better decomposition of the
issues that make it hard to understand cluster communication patterns.
There's the exercise of trying to answer "what *is* this script
doing?" and then there's also trying to answer "what *should* it be
I seldom felt like I had definitive answers for the later, but I can
see how it would be beneficial to do that and also broader
script/framework makeovers, possibly before 2.6, because it would help
inform whether new APIs are catering to "good" use-cases. Though my
thinking is it's not critical to get a 100% API/use-case match off the
bat and that there's some actionable stuff to take away from this
thread that is at least going to have us heading in a better direction
sooner rather than later...

Yeah, agreed. What I've taken away from your earlier points is that
these smaller changes are seeming like they'd be beneficial to do
* publish() API simplifications/compressions (pending decision on
exactly what those should be)
* enable message forwarding by default (meaning re-implement the one
or two subscription patterns that might create a cycle)
* see if any script-specific topics can instead use a pre-existing
What do you think?
A separate question/idea I just had was whether how much of the
process of auditing the subscriptions and communication patterns was
difficult due to having to hunt down things in various scripts and
whether a more centralized config could be something to do? e.g. I
don't know how the details would work out, but I'm imagining a
workflow where one edits a centralized config file with
subscription/node info in it and that auto-generates the code to set
them up. Sort of like working backward from the info in the PDF you
