Vercel currently ignores any pre-compressed assets that are uploaded, for example /_framework/dotnet.native.wasm, compressed to /_framework/dotnet.native.wasm.br, and appears to retrieve the uncompressed file, and do its own compression before serving it to the client. This is inefficient, as I compress my assets with a higher level of compression at build time. I believe the behaviour is the same for gzip, however I am most concerned with br (brotli).
Note that if you call or navigate to /_framework/dotnet.native.wasm.br directly in a browser or postman, you do get the original br compressed file (validated by file size and hash).
Current: Retrieves uncompressed file and performs own compression before serving.
Expected: Retrieves a pre-compressed file based on the incoming Accept-Encoding header, and returns that directly, without doing any of its own compression.
