 Right now, `wp_signups` (and the entire related API) does double-duty.
 It's 1 database table that's used for both users & blogs, but there are a
 few issues with this approach:

 * Open sign-ups may or may not include ability to create sites
 * There is no UI for managing sign-ups in WordPress core
 * Sign-ups are different between singlesite & multi-site
 * Plugins like BuddyPress do their best to include and/or work-around
 WordPress's core functionality, but end up writing a ton of additional
 code to manage this
 * Other membership plugins are forced to roll their own approach every
 single time
 * It's possible for multisite sign-up race conditions to exist, with users
 & sites created or activated from underneath each other (documented in
 `wpmu_activate_signup()`)

 I'm adding the multisite focus to this issue, because all of the current
 code is only relevant to multisite, but I'd like to see single-site
 inherit whatever future approach we can come up with.

 The core sign-ups code, stinks. Yet open registration is part of what
 makes WordPress & community/membership sites great. I think it would be
 great to take what we've learned from BuddyPress, WordPress.org,
 WordPress.com, and the bevy of Membership plugins, and make a great sign-
 up component/API for WordPress core.
