What does it mean for the ghosts to be "unable" to reverse direction? Isn't that just another way of saying that the original ghost AI was programmed to never choose to do so? There are, in fact, a lot of things they never choose to do. The whole appeal of this idea is to see if you can make better decisions than the original ghost AI.
Ghosts can only change direction at intersections. Otherwise it's just not Pac-Man. It's one of the many many other maze games from this time period. Pac-Man means something just as much as "vintage maze game" means something.
Should ghosts be able to go through walls?
