Well, it's kind of specific visualization's designer's choice, and my main complaint isn't something the authors of Turbo are unaware of (it's like that by design), but I think non-linearity of the light profile is far bigger downside than is being admitted. I'm not speaking about unable to print in greyscale or "people with the rare case of achromatopsia": it is actually harder for me to say at a glance what regions are hotter on non-ligh-linear image (or, more precisely, non-light-monotonic image). I will make mistakes when tired while working with Jet/Turbo images, which I won't make while working with Inferno. So if you use one and only one colorspace for some heatmap visualization, I think I would greatly appreciate using Inferno (or Helix, or similar) instead of Turbo in the most cases.
