Oh it's still pretty stupid, and I think they should have simply resurrected the Wordpad name for this, and maybe a conversion utility for opening doc/rtf files to markdown in the editor for older file support.
Edit is unironically one of my favorite text editors these days. It opens incredibly fast compared to everything else I use, it's easy to use, works fine on Linux. It's not going to replace emacs or VS Code, but it's incredibly handy for basic editing chores.
