Can we put them in LayoutTests/resources instead? I always find it hard to
remember the path fast/js/resources.

I support the effort to make layout tests more compatible with W3C tests.
Is the plan to use testharness.js for all new tests? Or only tests that we
intend to contribute back to W3C?

There is no such a guarantee at the moment? That concerns me. On other
hand, we wouldn't be importing ToT version of testharness.js so if such an
incompatibility is introduced, we can migrate our tests on time as well.
