That seems reasonable, since broken dependencies for 'dev' profiles |

aren't fatal anyway. |

It's also worth noting that we could do much more extensive |

dependency checks if we moved them to the server side. For example, |
| 28 |
we could check for problems in reverse dependencies such as those |
