I totally agree. With everything.

I am in full agreement that anyone working on the MS stack needs to know PowerShell. I myself have been using it on and off for 6 six years now but the problem is exactly that: on and off. Anecdotally, it appears that this is a common problem, however, once it is used more widely then those of us who script only occasionally are more likely to be using PowerShell almost exclusively. Also most deployments and installations of in-house software completely ignore PowerShell and it will take some time for this to change.
