@Aneurysm9 That's a good question. I took a look at using `SpanProcessor` but couldn't see how it could be composed with the `batchSpanProcessor` that we're currently using.

The use-case at the moment is for deferring non-critical work done in a request/response to happen after a user has already received the response. This primarily includes work that can't...

> @BlakeWilliams do you want to have a go at cutting the spec for this? Update `lib/rack/lint.rb` Definitely, I'll make some time to work on that.

Just opened up a draft PR that has a few open questions here: https://github.com/rack/rack/pull/1802

`Rack::Lint` seems to validate that middleware implements the spec correctly but `rack.response_finished` is completely dependent on the server implementation. Is there a standard way to validate that a server implements...
