Earlier quoted context omitted.
I have encountered it with many languages. There is usually a warning, but there is also a lack of consent on my part, and a lack of options to retain compatibility. For example, with most Python-based projects I have tried, I have run into some kind of version incompatibility, and often have not been able to get them to run at all. This is an experience I wanted to avoid for those who try my software.

That's exactly what I was talking about, and why I chose Perl as the "top-level" language for my project over Python, despite Python being very popular.
