Since the introduction of fuzz testing, there has never been a problem found because of a failure of a file in the fuzzer seed corpus. As the fuzzer has found problems, they have been added to the test suite, and that should be adequate to exercise the fuzzers in the tesing environment as well as providing adequate regression testing. Removing these original files shaves many minutes off the builds in CI.
