Your take on the correct solution to problem.
Make changes to use mkdirp@1.x

Are you willing to submit a pull request to implement this change?
Not sure. I could not find any references to mkdirp in the project. The reason I could not find anything is that it appears that the 7.x alpha version is now on master and it looks like mkdirp is not being used in 7.x.
