Mainly not waste too much power ;-) I used these for a variety of low power, low speed, moderately high voltage purposes. For example: Translating CMOS DAC outputs to higher and/or bipolar ranges. Buffering DC test points and temperature sensors. Thermal control loops. One advantage was that R&QA was reasonably happy with this choice, partly because it was available in a brittle ceramic package that was supposedly more reliable than plastic. I'm tentatively going with LT1078 for new designs. We'll see how loudly R&QA complains...
