I’ve seen a lot of discussion around backward-compatibility, minimal rustc versions and LTS releases in the past few days and I believe they lack a theoretical foundation. Therefore I did some math.
The resulting article may be found [here](https://github.com/teiesti/compdep/blob/master/compdep.pdf).
Please feel free to use this thread for feedback and discussion.
In case you find bugs or other shortcomings (even little tiny ones), please file an issue or a pull request on the [repository](https://github.com/teiesti/compdep).
