We have a multi-project solution, that has a "primary" project which would be the project to (also) version any time any of the projects in the repository change.
For example, if I have project P.Primary and P.Secondary; if I make a "feat" change to P.Secondary, I would also like for P.Primary to "inherit" the "feat" increment, even if there weren't file changes specifically within P.Primary.
Yes, I realize this isn't a standard project structure, but it's also not one I'm empowered to change. Your project would be a wonderful addition, if this could be possible.
