Yes, I think that's an accurate estimation. When the initial changes, which permitted some private rights of access, were made in 2002, there was a discussion at that time about including abuse of dominance. Since then, the proportionate support for it has increased, in part because there wasn't a stampede to the tribunal of everybody trying to bring a private action for everything under the sun.
In attending conferences, events and whatnot, I have noticed that there are a lot more panels on whether there should be private access. That's happened in a more concentrated way, I'd say, over the last five years or so, but certainly it's been out there in the environment for at least 20 years.
