It's not bad advice, it's Great advice. If you're at the leading edge of any technology, you haven't had decades of experience to fall back on to characterize the components involved in the configuration to which they'll be applied. All sorts of new problems cropped up once everything was in space. Clean metal surfaces spontaneously weld, for example. You obviously have to be well aware of the tyranny of the rocket equation, but you really shouldn't use that as an excuse to try to trick your way around problems in clever ways that are likely to cascade into mission failure and possible cost of the crew at the first little anomaly. You can't just pull over to the side of the road in aircraft, and space is even more unforgiving. There's nothing to stand on to lever against. Even a slow accumulation of sweat can drown you if you're not careful. Keep It Simple and Stupid is the bedrock of good engineering.
