Hi! 👋
Is there a particular reason to prefer gzip over brotli? Especially for perdominantly English vocabulary, brotli outperforms gzip both in terms of time and compression ratio.
Here's a quick benchmark I did recently: illagrenan/django-brotli#117

I guess the more general question is: what happens if the client accepts multiple encodings?
Like requests and aiohttp and probably most others do?

I don't think there's any reason to prefer gzip over brotli, though I suspect the answer is that it doesn't matter regardless because 99% of the traffic will be gzip anyways because the primary consumer will almost certainly be pip, which uses requests which, afaik, doesn't support brotli by default (requires extra libraries, and likely would get disabled in pip anyways because C libraries cant be upgraded on Windows if pip imports them).

At the point in the request that this happens, the Accept-Encoding header is normalized to only be a single encoding.
