rack.input was made optional in this [PR](https://github.com/rack/rack/pull/2018/files), which landed in 3.1. That broke rack-parser which always expects it to be present. This gracefully handles cases where it's not.

This change seems to be necessary for Rack 3.1 support but not sufficient. The rack.input is no longer required to be rewindable and can be closed (perhaps by some downstream middleware?). https://github.com/rack/rack/blob/main/CHANGELOG.md#spec-changes |
