I think you're fine with early steady...you obviously knwo your dog that it's ready.
I have a high drive Golden that I taught to steady very young so she could focus on marks. As a result, she passed her UKC started test on water at 5 months old, the same test you set up in Vermont as a double for Seasoned!
And she's still doing great, earned a WC at 8 months old, which involves a land double. It has not harmed her marking abilities at all, if anything, improved them.
I think steadying her early helped her immensely, but as others have said, it depends on the dog.
So my vote is with you.
