A high cantle, deep seat configuration is made for somebody who likes to ride with feet forward, braced against the cantle. Very common, and saddlers build saddles for that, because people want them. Lots of ‘Wade style’ slick fork, post horn saddles made that way.[/QUOTE]
Like the shape of the fork, there’s nothing about the cantle that determines anything about the way a saddle rides. How hard it is to mount or whether it catches you in the back, sure, but not where your feet end up.
What determines whether a saddle is legs-forward oriented is the relationship between the lowest point on the seat, the location of the stirrup leathers, and the width of the stirrup itself. If the distance between the low point on the seat and the place where the ball of your foot rests is about the same as the length of your foot, then pressure in the ball of your foot won’t send the stirrup forward. If that distance is much greater, then pressure will kick the stirrups forward.
That’s why a saddle that rides fine for a larger person won’t ride the same for a smaller one, or why adding wider stirrups can correct issues with stirrup leather placement.
In fact, most older saddles in the CA tradition (typically very deep seat, high cantle) ride very balanced because the seat length is much shorter. Newer, especially pleasure or reining type saddles that are MUCH longer then the older ones are much more likely to be “dashboard” type saddles.

Older saddles also tend to have much flatter seats then newer ones, which allows more flexibility and doesn’t encourage poor position. If your personal conformation doesn’t match a quick rise saddle, it will tend to kick your feet forward as your pelvis rocks back. Even Mr Dorrance’s Wade was build like that:
