Caching of hydra:ApiDocumentation and Entrypoint

For using the json-ld/hydra API I have to check https://demo.api-platform.com/docs.jsonld and https://demo.api-platform.com/.jsonld to figure out the types and operations which means two extra requests before the first real API call. These requests aren't cached, and slow things down.

I wonder if this couldn't be cached with etags since the content is static anyway. Am I missing something maybe?
