I'm not really sure what a gradual change would mean. We need to replace the whole sprite class, and continuing to support ZScript after that means making a separate version of the script engine to work with the new classes. Changing the combo system would mean all the scripts using Screen->Combo* or Game->Get/SetCombo* break. Same deal for flags. The whole itemdata type depends on the current weapon implementation. There are all sorts of weird little things; weapon->DeadState, screen flags, the behavior of directions outside the range of 0-7... How far do we go to keep existing scripts working? And if we're okay with breaking scripts, why go to any trouble at all when only the most trivial will keep working?
Maybe it will become clear in time. It's not like this is something that's going to happen overnight.
