Comment:

 34659.2.diff supports whitelisting specific functions to only receive one
 argument when used as sanitization or validation callbacks

 On Slack, we also
 [https://wordpress.slack.com/archives/core/p1447873482000901 explored] a
 couple other options:

 * Only ever passing one argument to the validation / sanitization
 callback. But, the extra context can be helpful, as we're using in the
 plugin itself.
 * Introducing an ancillary `validate_callback_single` argument, which
 would only pass one argument to the callback. However, this doesn't seem
 very glamorous.
