Please revisit your CMS idea. They're still around, like Kirby and others.
You are right about the old templating systems. I still use them. I still use PHP, it's ridiculously fast and mature. It has a readability unmatched by other languages (for devs like me with design background).
I'm surprised to hear CS people like yourself talking up the old templating systems!

For me, modern web dev is about modern CSS and JS and native browser APIs and all that fun stuff. It's ironic now with LLMs, the people caught in the grinding gears of MVC bloat are benefiting least from LLM.
Well, perhaps I can't make that claim, but the point is LLMs do a fantastic job at focused, single-layer arrangements such as the good old templating systems, vanilla JS and just direct "old school" frontend coding. Why burden ourselves or the LLM with truck loads of layered dependencies or a million steps to hello world? No need but people get angry on this topic though, so I just do my thing in my corner of the web and deliver results for those I build for.
