[theme-reviewers] Submitting a One-Page Placeholder Theme

[Chip Bennett]

I was trying to start from the most-simple, and work toward more complex as
necessary.

At the simplest, the Theme developer documents the "niche" nature of the
Theme in readme.txt, and explains its special usage. At the same end of the
complexity spectrum, the Theme developer adds the special-consideration
rationale in as an in-ticket comment, before the review commences.

At the more-complex end of the spectrum, but easier on the Reviewers, we
would have a submission form to request a theme-slug to be white-listed,
with an explanation of the "niche" nature of the Theme, and rationale for
special consideration.
