It would be great to be able to handle/respond to step (or even step actions potentially). The use case I have is a deployment slack bot. At the moment with the current build status webhook I can only notify the slack channel if the build succeeded/failed, it would be great to be able to handle this in more granular context without polling (I’m building the slack bot using AWS Lambda so the 5 min execution limit comes into play on longer builds ruling out polling at the moment).
This would certainly pave the way for richer ChatOps functionality and other great interactions with CircleCI potentially
PS. Keep up the good work on v2.0, loving it thus far!
