Changes to the script are necessary, and whether they're made all at once or incrementally the end result is the same, that is, there would be the same amount of doubt that they're still reporting correctly.

Yes exactly, so long as each change is coherent.  If you look at the patch it's got a lot of renaming to make the vocabulary more consistent, code simplification, etc that spans the html as well as js files.  It would an unreasonable amount of effort to try to separate them.

After this change I hope to make the tests more clearly targeted, if possible.  I just want to make them manually testable for now, to help with another patch I'm working on :)

And if we had LTR/RTL results on separate files, people are very unlikely to realize that those results supposed to match.

Ok I agree, thanks.
