It's safer to try for clean passes (obviously), simply to avoid both the risk of mechanical failure or the risk of the stewards coming down with a random ruling this year. 

It's similar to Rugby where someone tries for a try with 10 people crowded around and over them.  They might well have scored it, but with no convincing footage to fall back on it's risky.  Much safer to pass out wide where the try scorer is in free space and there's no room/need for it to be reviewed.

A quicker, more transparent ruling process would really go a long way here though.  In this case you would simply order Verstrapon to give the place back, and then we all move on.  That's a much better outcome than a process that takes longer than the whole race and leaves everyone in limbo as to who might have won etc. 

Hard here because it happened right at the end, so little time before the podium etc, but a simple place swap order could have been applied straight away.  We need rules that deal with issues like this quickly and consistently, without the racing becoming sterilised by pedantic rulings that hurt the racing aspect.  In this case there wasn't a wall there, Leclerc simply ran wide onto sealed tarmac over the kerb and didn't crash and neither car sustained mechanical damage.  Contentious ruling therefore = give place back and get on with it.  Works for me.
