It does not necessarily make a case for avoiding such clearances, but it does show how spectacularly things can go wrong if someone loses the plot.
More so, it made the point about operating in two languages. I don't think the crew of the Shorts could have had the plot in the first place because of that.
I use conditional clearances all the time, within the rules in MATS Pt1. You have to, to make the traffic move. As regards creeping over the line, we have one hold which is back a bit further because of the taxiway geometry and its uphill. I don't mind a bit of 'creep' against another departure but not against a landing and I will say something if I see the departure moving. Most crews play it this way.
