Would to_mdast() return variants of mdast::Node other than mdast::Node::Root?

[lo48576]

I haven't read the parser thoroughly, but it looks like to_mdast() always returns mdast::Node::Root(_) on success, even if the source document looks like a simple "inline" text.
If so, isn't it natural and explicit to return mdast::Root directly instead of wrapping it to mdast::Node enum?

Or if it can return something other than mdast::Node::Root(_) variant, the condition would be worth documented.

I'm wondering my converter over md AST can assume that the returned AST is always mdast::Root.

Hey! It does indeed always return a root. I don’t have strong opinions on this. The AST can be improved though. That’s one of the main reasons this is still alpha. There are different issues about it.
