In principle, yes. Albeit as part of a bigger picture. Back then, we mostly focused on the booking classes and what would be Individual Travel Request Generation in the new system. This would have been a great improvement, but mostly due to the latter. The former would have added a lot of (interface) complexity for a fraction of the benefits.
The new booking classes will resemble their real-world counterparts much more closely, especially due to the introduction of fares (which we didn’t dare touching 8 years ago, I think mostly because I didn’t grasp the subject as well as I do today).
