Which puts limits on the operator, and where they can go. Believe me, I worked out of Van Nuys for a few years, flying the same jet you fly. When 16R was closed(It happened a ton in late '11 and early '12 when they were spending up the budget), we would reposition to BUR before it closed so we wouldn't have to tell someone "Sorry, the long runway is closed, and we can't depart with that much fuel legally." All the companies that I still talk to out there that I actually have respect for repositioned before the runway closed, well, at least the ones I would work for. Telling a broker that you can't do something is bad business. The majority of them don't look at NOTAMs and the majority of them will start looking elsewhere.
To say that no one has failed to properly plan when in the same breath you also say "it puts limits" is a misnomer. It does for a lot of the aircraft based there. Plus, there are a lot of airplanes that will be to heavy to depart 16L. Try doing a trip in a -55 off the short runway with enough fuel to get any kind of resonable distance and have the numbers. A Soft V1 isn't going to cut it (whatever that means). It's a V1 number for a reason. What happens if after "soft" V1 you have a failure, and decide to continue? That number is that number for a reason.
Take the airplane to a runway that is long enough before the long runway is closed, or buy one that has the performance to operate off the short one.
If the AFM and OpSpecs allow it, then do it, you have no excuse at that point. But when the AFM says you can only take enough fuel to make it half way to where the customer wants to go, and you have to plan a fuel stop, the broker will likely go looking elsewhere, likely to the company that took the time to reposition to BUR (a 10 minute drive from VNY). I know that because I've seen it happen, at that airport.
