This is a high priority feature, and will likely be targeted as soon as possible after v17 ships, though it is not yet committed to a release.
This feature is under consideration for a future release in 2018, though a target version is not yet set.
This is being considered. The current intention is to add a superadmin role, making the default admin account just a member of that role.
This will allow you to create new superadmin accounts, capable of logging into the shell, adding ssh keys, and any other features limited currently to the named admin account.
Second, you will be able to disable or demote the named admin account.
