Three big differences in comparison with Erlang: 1- Cannot externally kill a process (yes, ergo process have a Kill method but the process will be in a "zombie" state until the current message handlers returns... maybe stuck forever) 2- No hot code reloading. 3- No per-process GC.

(Not affiliated with Ergo) I have been watching Ergo repo for a while now and you wrote my observation concisely.

A while back, I tried to solve no.2 on your list by having a dynamically expanding and shrinking go-routines. POC here: https://github.com/didip/laborunion. It is meant to be used in-conjunction with config library & application object that's update-able over the wire. This idea is good enough to hot-reload a small IoT/metrics agent, but I never got around to truly solve the problem completely.

That could be another way to have AWS not poach a popular Open Source project. Name it something extremely pro-unionisation, such that every time they write the name they'd be reminding their developers that unions exist. :)
