This seems dangerous to me, as any term can now be disguised as Parent. The same for TypeTree. Conceptually, how it is different from making Parent a supertype of Term and TypeTree?

It is not conceptually different, but it solves the ambiguity in the extractor when passing a Term as term could be a Tree or a Parent. This will be removed when we bootstrap and I'll be able to define type Parent = Term | TypeTree and have a simple extractor for both.
