 are you hypothesizing?

 Continued hypothesizing only because I recently learned... In b2++, the
 username/sitename slug was first used as part of the table name (e.g.
 `wp_jeremyfelt_posts`) before it was switched to blog ID. This may have
 been a driver in some of the original sanitization.

 Moving this to 4.3 because we have tests, a patch, and a full cycle ahead
 of us.
