With the diversity of processing units, operating systems, network based storage, software defined networking & other contemporary IT, it makes sense in some circumstances to not use Microsoft Windows as the core operating system when seeking the best performance.
It would be good if Esri could publish a roadmap for non-Windows based versions of Pro.
Please do not just close this idea - I know it has been floating around for a while but formalizing it and being prepared for it when necessary is better than waiting another 9 years once ARCGIS Next is released.
