"Your Let’s Encrypt client used ACME TLS-SNI-01..." Which one?

Are redirects from HTTP to HTTPS during certificate renewels considered to be HTTP-01 or TLS-SNI-01 currently? Are those redirects still supported after support for TLS-SNI-01 has been removed entirely?

There were questions around those redirects in the past and they mentioned those as supported:

I don’t think all of this is necessary. The HTTP-01 validator is willing to follow redirects, including redirects to HTTPS. I think a number of people have continued to use webroot successfully on servers that perform a blanket redirect from the HTTP site to the HTTPS site.
