@klardotsh there's something about hand-writing HTML, like ... as soon as you have two pages that need the same header, or a shared sidebar, you have to either sacrifice DRY or sacrifice "I'm editing the files exactly as they are going to be sent" which is legitimately an annoying tradeoff
I mean, I do it anyway, because m4 is a *very* small abstraction to place on top of it, but I think I get why it puts people off?
