Does FSD beta replace all legacy Autopilot suite software for HW3 vehicles?

[boiler81]

I don't have FSD but have been following the FSD beta release videos.

When folks with FSD beta get on the freeway, it appears as if the legacy Autopilot software/graphics are used. This made me wonder if all the legacy Autopilot (i.e. autosteer, TACC, NOA, Smart Summons, Auto Lane Change, and Autopark) functionality/software get replaced with the FSD beta rewrite now or in the near future?
If so, do you think Tesla's support for legacy Autopilot software (HW2.0 and 2.5) will disappear in the coming years?

My guess is the perception neural nets will change and benefit AP/EAP while driving policy will be different. I just can't see them maintaining two competing models when clearly all their eggs are in the FSD basket.
