There are exceptions to this for images and other similar resources, but otherwise the policy for most repos is to avoid binary files'. Skara is able to identify binary files when executing jcheck, but this check is not enabled.

What I think we want here is an informational message for Reviewers rather than a warning. So a message in the Description that says something like "__Note__: this PR includes binary files" might be sufficient. I don't see the need to be more nuanced than that by checking the type of binary files.
