Thanks for the feedback! I have personally heard this request from a number of customers. IMHO having the ability to use GMS accounts would be a quite useful in DSC configurations. If this is an important feature for you as well, vote it up so that we can appropriately prioritize it as we move forward.

I've been thinking about this since running into the problem myself. The thing I'm thinking now is to keep the behaviour of credentials not allowing blank passwords (because it's difficult to create a secure string on a blank object).
Instead, have the resources check the credential's username, if it ends in a $ symbol (required for Managed Service Accounts), ignore the password.
It's what I'm about to do, although I don't like changing the DSC resources from the gallery too much but I'll see if it works then submit a PR.
