Could the process to replace them on, say, public transport be outlined?

It highly depends on your jurisdiction and other regulatory requirements thus I gather there is no comprehensive answer to this question.

Alternatives could be any of the following:

* Not using a captive portal at all i.e. having just a free WiFi
  for everyone near enough to receive the radio signal.

* Using WPA Enterprise (RADIUS) to have users login without any
  website but directly as part of joining the network. This works
  for very large networks, too. E.g. the `eduroam` common in some
  universities can be accessed from any of the participating
  universities' accounts by just entering their campus e-mail address
  for login.

* RFC8910 - Captive-Portal Identification in DHCP and Router
  Advertisements (RAs). I never never heard of it before searching
  for “Alternatives to captive portals wifi” online :)
