PRT has become a standard for saving/manipulating data. Fast, reliable, light, and powerful with magmaflow data manipulation, and works on multiple platforms. (max, maya,cinema4d,realflow, and much more)
Even on max 2018 we can export PRTs (only on fluids).
We need a way to import PRTs in max by default. Right now only PRT importers are with the main krakatoa plugin, or with Thinking Particles. A build in loader (creating one by max devs, or with an agreement with Thinkbox), will be highly beneficial for multiple sectors that needs heavy mesh scattering.
