-w '%{redirect_url}' doesn't work with -L

[LLFourn]

I did this

curl -L --max-redir 0 -w  '%{url_effective}\n%{redirect_url}\n' -s -o /dev/null 'https://httpbin.org/redirect/1'

and

curl -w  '%{url_effective}\n%{redirect_url}\n' -s -o /dev/null 'https://httpbin.org/redirect/1'

I expected the following

Them to be the same. Although the documentation does mention it doesn't work with -L, if curl stops following redirects because it hits --max-redir it makes sense to me that the final redirect response should put its url in %{redirect_url}

(I guess this might be feature request?)
