What is the use case for textedit in 2023?

I think the main usage of textedit is to edit RTF file as that is the default format textedit uses to save files. But even Microsoft doesn't seem to use RTF format anymore, "Microsoft has discontinued enhancements to the RTF specification" and as "In a 2020 insider build of Windows 10, WordPad is modified to include advertising notifications for the Office web apps as an alternative." I think one use case for RTF file is for **cross-platform sharing**, but we have other file formats for that (pdf, md). BTW, I always find the name "**R**ich **T**ext **F**ormat" is a bit misleading. Any text editors online now have some kind of so-called **Rich Text** Format support, e.g. as I am writing this question here, but they are NOT the rtf format we were talking about when using textedit (or WordPad on Windows). So what is use case for TextEdit in 2023?
