I think that's a fair conclusion honestly, though the cynic in me does want to point out that people do integrate their work against slack and that is difficult to maintain in parallel.
Netsplits are mostly a solved problem these days, both with increased reliability of the internet and with network failure proxies like RobustIRC (for the linking protocol); and I remember fondly the times where we had a single IRC instance for all of our company (which had people working across: Thailand, USA and N.Europe) without issue.
But, yeah, I think what you said is completely fair.
I mean I've seen weirder. For Slack specifically I had a fight with a dev team because their deploy tool failed if it couldn't push a message to Slack.
