Would a new_root_span! macro be useful?

[Nicolas-GUILLAUME]

Hello,

Today I ran into a situation where I want to create a "detached" child span. Unless I'm missing something, this is unfortunately rather verbose to implement via the Span::new_root method.

The span! macro unfortunately only supports creating spans with Span::new and Span::child_of. Looking at the macro I feel like adding a new new_root_span! macro would address this gap and wouldn't be a very intrusive change. What are your thoughts on this?

So dinging into this more, there is a way to do this easily with:

span!(parent: None, ...)
