Notifications are easy, do many companies really use more advanced bots?
If we need to switch to a different messaging platform, sending that same notification at a different api should be pretty trivial. And if it isn't, I don't know why we'd be switching.
- deal with the target platform's API
- deal with APIs of the many platforms that are being integrated
- maintenance and SLAs
I honestly doubt you can create half a dozen good integrations that require more than just notifications in a channel (for example, PagerDuty notifications and the like).
