Totally agree on edge case quirks of MJML - or more like weird behaviors in Outlook. With so many email services and clients around, nothing can provide 100% bulletproof solution but I think MJML is as close as it gets to works-for-majority. I‘m sure MJML maintainers also aim for this.
Also, yes! Microsoft should kill Outlook with fire! :)
