Great idea! Definitely re-using this for https://github.com/swissspidy/media-experiments to check the content type of WASM files.

I can't remember the specifics of escaping fields like this.

Escaping for labels is only included in plugins/performance-lab/tests/data/class-site-health-mock-responses.php, maybe we should remove it there.

Thanks for the PR. Left some feedbacks.

Does it possible that Site health shows Your site does not support AVIF as failed but Your site sends AVIF image headers return headers 🤔

@mukeshpanchal27 yes, it is possible - AVIF server support and AVIF file header support are two very separate things.

Begs the question: is it worth adding this health check if the server doesn't support AVIF files anyway?

That's my next question. Thanks @swissspidy for asking.

I thought about that and I'd say yes - one reason is you could potentially migrate a site with AVIF images to a new server where they still need to get served. Also, AVIF files could be included in the theme even if not supported by the server for uploads, eg as part of a template.
