Hey, @futtta . Celso Bessa, AO pt-br translator here.

As you know, HTTP2 push is a big deal in optimization now. We are getting great results in some of our projects with it and I think it would be great if AO included a mechanism to use those headers.

In some test setups we filtered AO final JS/CSS srcs and created our own headers using PHP/WP send headers ( https://codex.wordpress.org/Plugin_API/Action_Reference/send_headers ). this is not hard for us, but it might be not easy for an non technical user.

In other setups we used AO alongside http2 server push plugin by @daveros ), which is great, but it sends headers for all files in the original wp_enqueue queue but not for AO aggregated files (my guess is it uses a hook triggered before AO).

Looking this 2 cases, seems to me that having this on AO would help a lot of you user base.

What do you think? I won't be able to code anything for the next 4 weeks, but if you think it's a good feature, I can work on this in august.
