Exactly, is the proposal a move or an addition?
* If the proposal is to move, this will "solve" the fragmentation problem
(there's only one) but would create a massive alienation problem (enough
people in the community would be really angry).
* If the proposal is to add a new one, then we'll have the same problem as
IRC vs. Discord and fragment the community, which would continue working on
their own, but disconnected.
On the topic of "fragmentation", I would argue that is to me a great

I don't think there's any feature in the new tools that would "fix"
fragmentation because enough people in the list would just not use it,
however wonderful it is to some people.

I challenge this. Not because I love mailman (I really don't), but because
mailman has a lot of features for sub-communities for decades.
I'm not saying it's easy to setup or intuitive to users who had no contact
with mailing lists before, but they exist and other communities use them.
I've seen enough back and forth in all the threads on this subject to
realise the "impedance mismatch" is more of a generational thing (people
who dig new tooling vs. people who find it hard to change their ways), than
it is a technical thing.
Finally, one last advantage of Discourse/Discord over mailing-lists/IRC is

I'm not an expert in mailman but I believe this can be done, too, with
mailing lists. There a lot of options for sub-lists, aggregation lists,
cloning settings that can be done to make that work.
Even the fact that llvm-dev@ is the place to organize the entire project is

Absolutely, but that says more about our ability to manage mailman (and
other infra) than our desire to have organised communications channels.
We're compiler engineers after all.
So, this is not about which tool is better, but how to we optimise
communication. And whatever the real answer ends up being, replacing one
tool with another definitely isn't it.
For context, I was born with a brain that doesn't adapt well to
environmental changes, especially if they're not central to what I do.
Communication is affected the most.
After more than a decade working with LLVM, I've come to know enough people
like me in our community that a change in the communication style would be
Some of them are already gone because of similar past changes, and I think
some people were happy to see them go because of that impedance mismatch.
"They don't think like I do, so they're better gone".
So, while I welcome new participants to the project, I'd really like to not
have to choose between them and the people I know can still deliver radical
changes to the project and have done so repeatedly.
My proposal: instead of discussing which tool is "better", why not discuss
how can we move to a new tool without breaking the communication model that
people (like me) would find too radical to change?
If the tool you propose can't do that, let's find a new tool. Let's work
with that tool to improve it. Let's do something.
Anton K. is doing a remarkable and thankless job at trying to get a better
git repo and issue tracker, despite ferocious impediments. His aim is to
keep the status quo as much as possible while moving on to better tools. It
takes a long time.
I think we should follow his lead in this discussion, and try not to force
people to pick sides. THAT is what creates fragmentation.
