// assign a milestone to issues or PRs added to a project, with a name corresponding
// to the name of the project - create the milestone if it does not exist
//
// adding a *second* project to the issue will update the milestone accordingly

// and, no idea what happens if one very quickly adds and removes an issue
//
// an issue or PR actually becomes a card (or, a card is actually created...) when
// it's move to a project column for the first time - being assigned to the project
// and showing in project's backlog is not enough.
