We have no interest in stabilizing Rust 0.5, 0.6, or any earlier version. They are versions of the language that are useless for our needs—they weren't even memory safe (and fixing that required breaking some code).

The most realistic way to address your criticism would just to have been to keep the language a secret until it's mostly stable. This is what most other companies do (for example, this is what Google did with Go). But then you couldn't use it at all.
