If a noun clause acts as the subject of a sentence, is it no longer a dependent clause?
For example:
- "What he did was outrageous."
I just saw this on a site so I wanted to see if it's true or not.

[What he did] was outrageous.
"What he did" is not a noun clause (even if there were such a thing, which there isn't), but a noun phrase in a fused relative construction.
The pronoun "what" is simultaneously head of the whole noun phrase and object (in prenuclear position) in the relative clause.
It means "That which he did* (or the thing that he did") was outrageous".
EDIT: Below is a tree diagram of a similar example showing the structure of a fused relative construction with "what" in prenuclear position. As the diagram shows, "what" is co-referenced by the i subscript to the direct object in the nucleus clause.
