I was thinking part of Office 365 - collaborative dev tools are the missing piece for most businesses.

There wouldn't be a major need for Jira, GitLab, etc for the most part.

I don't know why this is downvoted.

I've worked at two major companies which both used MS Office/Skype for everything and a selfhosted gitlab for code repo.

If the MS package provided git, I'm sure we would be using that instead.
