You have a fact there, but you're extrapolating it too far.
Yes, fingerprints on halogen lights are a problem, because they run very, very hot. The extreme heat means the skin oil will thermally stress the crystal glass and crack it.
Plain old tungsten incandescents don't get that hot. Nor do "modern" incandescents that are a tiny halogen inside a glass bulb shape - the large surface area of the traditional bulb shape cools them. So fingerprints there don't really matter.
Likewise they don't matter on LEDs, but I wouldn't go touching LEDs because they have typically metal heat-sinks, and a lot of them have extremely poor or nonexistent electrical isolation to the heat sinks, so they sit there in the fixture energized at 120/230V. Even if properly designed, the heat sink may be bonded to neutral, which is hot if the lamp or house is mis-wired. With 100 million DIYers installing fixtures and smart switches, mis-wiring happens all the time.
Really, the heat of halogens is a 20th century problem. They were scandalously banned after countless house fires, plus being a horrible burden to the power grid - 500 watts for a living room light? Remember those "torchieres" that were everywhere in the 90s and you notice they all sort of disappeared after about 2000. Because of the fires and lawsuits!
Honestly there was nothing wrong with the torchiere concept, bounce the light off the ceiling. Now you can do it with about 40 watts of LED, not bad at all.
