By linking against a supported Perl version, we can protect Vim users from potential vulnerabilities and ensure a more robust editing experience. It's like upgrading from a rusty old bicycle to a shiny new motorcycle – you get better performance and peace of mind.

Furthermore, staying current with Perl versions allows Vim to leverage new features and performance improvements. Each new Perl release brings enhancements that can benefit Vim's functionality and efficiency. For example, newer versions of Perl often have better support for Unicode, which is crucial for handling text in various languages. Think of it as upgrading from a black-and-white TV to a vibrant 4K display – the experience is just so much better. Additionally, linking against the latest Perl version ensures compatibility with other tools and libraries that Vim might interact with. Imagine trying to plug a modern USB-C device into an old computer with only USB-A ports – it just won't work. Similarly, Vim needs to be compatible with the latest Perl ecosystem to function smoothly.

Beyond security and functionality, using an unsupported Perl version can lead to practical issues for users. For example, if you encounter a bug related to Perl 5.32, you're unlikely to find a fix, as the Perl developers are focusing on supporting newer versions.
