New description:

 If no protocol is specified for esc_url the function will automatically
 prepend the http:// protocol. This is likely now the wrong assumption, but
 potentially can break backwards compatibility if changed, since developers
 may rely on this.

 So this change proposes an additional parameter to the function to specify
 a default protocol, keeping the old default but now allowing for one to
 ask for https://

 This came up in this ticket:
 https://github.com/WordPress/gutenberg/pull/30100

 The usage could then be:

 {{{
 esc_url( $url, null, 'display', 'https://' );
 }}}
