Well, it may not be a "big deal" if the said PSU is fairly straight-forward to dismantle and repair. Seriously chunky jobs like the Farnell TSV70 (for example) are anything but - and they are large and extremely heavy! Then there is the inconvenience of doing a repair, of course. However, I've come across that short-coming on many a commercial bench-top PSU. But a fix is easy, of course: a diode, reverse-biassed across the voltage output terminals. A diode with a hefty current-rating would seem a good choice.
