That's so dangerous
Worst case scenario i'll use the rear brake to modify my trajectory, but using the front brake when you're engaged in a turn is a huge no-no.
It's not as dangerous as it seems, I'm braking late and hard and deep into the corner with very little or no lean, off the brakes, tip the bike, turn, start adding throttle progressively once the exit can be seen. Not the lines a sports bike rider would choose but it's a very fast way around a set of corners on a DL.
The only dangerous bit is that I'm closer to the outside edge of the road than is typical before I initiate the turn. On the other hand a DL with semi-knobbly tires doesn't automatically crash if the seal runs out and I've reduced the chances of becoming a hood ornament for oncoming traffic considerably.
IMHO skimming the apex of the corner which is the traditional 'fastest way round' is far more dangerous.
