 Replying to [comment:18 sujin2f]:
 > @jeremyfelt I don't understand why did you want to set an action because
 there is wp_signup_location filter already. If we make a new action,
 people will have to set one filter and one action in order to change the
 signup location. Just for preventing redirection loop?

 Correct. Someone would probably have the easiest time redirecting `wp-
 signup.php` manually at the server level, but for those needing to force
 it via plugin, a second action to short-circuit the file should be fine.
 Reliance on the current `wp_signup_location` filter is a bit iffy, mostly
 because we would need to compare it with `network_site_url( 'wp-
 signup.php' )` which could also be filtered. We could make an attempt at
 comparing it with `$_SERVER['SCRIPT_NAME']`, but I'm not sure how reliable
 that would be.

 The use of a new action allows for a general short-circuit of the `wp-
 signup.php` load and would also help anyone trying to replace the signup
 experience without changing the location. It also aligns us a bit more
 with what actions are available in `wp-activate.php`.
