Like wise with both Bat (rust) and Glow (go), the most popular command-line "colorized" viewers: only files ending with .md will be correctly rendered as Markdown. As this README.source file is intended for humans to read, and using Markdown in READMEs is popular, I only see benefits (for humans) in allowing Markdown in this file, and can't really think of any downsides as autocomplete will find this file with any suffix easily as long as nobody accidentally go and add two READMEs, which is unlikely.
