Yes, sorry, wasn't saying that either Go or Rust were an exception, just trying to forestall the inevitable "but what about X thing that was used by everyone and is still 0.9" :)
For Go vs. Rust, I think a comparison of 1.0 releases is perfect.
I think gp meant that for some platforms it can make sense to count even 0.x releases (nodejs is the best example I think), even though for most it doesn't (including Rust and Go).
