I believe it also would be great to have a `seed_corpus` attribute here pointing
to a directory with a few test inputs (something like test inputs from
http_security_headers_unittest.cc).

Thanks for the tip! I added a seed corpus of the de-duped unit test values from
http_security_headers_unittest.cc. (The HSTS/HPKP/Expect-CT headers are similar
enough that I just used the same corpus for all of them.)
