Sorry for beeing late to the party.
I wonder whether we can simply expose a flag served_from_cache or something
similar instead of the whole metadata.
Is there anything that would prevent this?

Reasons for exposing all the request metadata:
- Future proof: When someone needs one more flag in the future, we won't have to
update all clients again.
- Consistency with what ImageDataFetcher does.
And I don't see a reason for *not* handing out the whole metadata - do you have
any particular concerns?

I prefer the current way as I will need to expose response headers to the
client.
Exposing RequestMetadata would simplify my job heavily.

@Marc:
No need to be consistent with the ImageDataFetcher. It's a different layer.
Re-Future proof. You never know what the future brings ;-) I don't think this
will make anything more ore less future proof.
Jan gave one example - exposing technical details like HTTP headers.
@Jan: What HTTP response headers do you need?
The reason why I'm challenging this is that returning a bag of things is usually
a easy way for exposing details that may not need to be exposed.

But it's still the same overall API. I'd find it weird if data is exposed from
ImageDataFetcher, but ImageFetcher keeps it to itself.

IMO even if we only have these two things, it's worth packing them into a struct
rather than handing out individual random things.
FWIW, we went through the same process with ImageDataFetcher: First expose one
flag (and update all clients), then another (and update all clients), until we
added the struct.

Well, we do have concrete use cases for the things we expose. IMO packing them
all into a struct is really a minor details, which just reduces churn.

@Markus:
I need the response headers for integration with Google favicon server.
We agreed that they send an additional piece of info (the original URL of the
icon being returned) via the "Content-Location" HTTP header.
