I know a ton of work goes into making Octane and I really, really appreciate it but I do agree with you on this one. If we want a solid ecosystem I think it is really handy when you adhere to certain "industry standards". At least to an extent - supporting the mix curves and all that. Having the ability to at least somewhat properly convert materials from other renderers also comes really handy because then it's a lot easier to work with assets that you get online. Easier access to assets = more content.
So yeah, with all due respect, +1
Plus, that bicycle image... Haha!
