Bun seems really compelling. I tried it out for a couple of small example projects and I like the speed and the fact that it combines package management and a JS runtime. However, I use Dependabot on most of my serious projects. I know work is under way, or at least there is some discussion in a couple of repo issues, for Bun support in Dependabot. I'm kind of holding off on using it until support for it has been rolled out.
We had the same reticence about Dependabot missing before we made the switch, but realised Renovate works with Bun and is a good enough stand in for now until support arrives.
Absolutely zero regrets, the cumulative savings across everything that is faster and the massive step up in DX is worthy of the hype.
Original SGML was actually closer to markdown. It had various options to shorten and simplify the syntax, making it easy to write and edit by hand, while still having an unambiguous structure.
The verbose and explicit structure of xhtml makes it easier to process by tools, but more tedious for humans.
It’s kind of a huge deal that I can give a Markdown file of plain text content to somebody non-technical and they aren’t overwhelmed by it in raw form.
HTML fails that same test.
