To me it raises a concern, chatops and slack integrations are /very/ common, it's a form of vendor lock-in on their side and it makes absolute sense.

However, if you become dependent on chat-ops to do your job. (say: fallbacks for common things have eroded due to lack of use) then suddenly your company is crippled. And why? for a chat service? The value add from slack is grotesquely small in isolation.
