To be clear, this is the current limit in beta and it's per repo, so if you have multiple cloud projects, you get multiple repos. We're thinking about adding support for multiple repos per project in the future. Would that be useful?
Also, and we're planning on upping the limit once we reach GA. What do you think a reasonable limit should be for a git repo? Our goal is to strike the right balance between usefulness and abuse.
You should absolutely support multiple git repos per project. If someone writes npm-compatible modular JavaScript code, it wouldn't be hard to have a dozen proprietary repos supporting a single reasonably sized project.
