Comparing 1.0's is a much better comparison, except in cases where there was huge adoption before 1.0.

I wouldn't say rust was hugely adopted before 1.0 (not that it's hugely adopted after, either).

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).
