Allow group managed service Accounts (gMSA) to have a dummy password
It's 2017 and there's still Server Software (even microsoft's own - like TFS), which is not able to handle gMSAs, because the password field is mandatory.
Since that software probably uses windows function to sign-in as such a user, it would be nice to have a mechanism, which allowed us to just use a dummy password for such an account - like "groupManaged" or "-" whatever else.
So perhaps this is possible, that Windows Server introduces a mechanism allowing to type a password in the mandatory password fields, which signalizes the same as an empty password for gMSAs.

Many applications that require password for service accounts should change the behavior and upgrade their code base to work with gMSA. As far as I understand, this is against the architectural decision of gMSAs. But I agree with you and it had come to my mind when I worked with several software that require password even for gMSAs and I had to use an old-fashioned service account.

If I understand correctly, you're essentially asking for an option to set a "fake" password on a gMSA that AD will accept as valid, but not actually give you a valid auth token for?
Wouldn't that just break a bunch of apps who explicitly try to use the fake password when they authenticate with the account, think they've succeeded, and then fail to do what they want to do?
