stuff like this is one argument I have against language version deprecation. Python 3.* is great for example but in the year 2199 people should still be able to write and use python2.7. That doesn't mean someone has to keep adding features or fixing non-security interpreter bugs. It just means the last release version is made available by python.org and support by OSes forever. Same with perl, rust,golang,etc... Languages are not dialects, even in computing.
