although I’m a little bit skeptical about having to integrate additional extensions and workflows
Just to allay your fears, it’s not a mishmash of random extensions and brittle workflows.
11ty was originally built in a more all-in-one box style, but it was kind of annoying to have 10+ templating languages to choose from (and all the dependencies that came along with them), when you only wanted one.
Every update, the author does two things:
- Splits more functionality into first party plugins
- Removes, or forks and takes over third party dependencies.
You can see that here: (data taken from here: https://www.11ty.dev/blog/dependency-watch/#full-history)

The first-party plugins are all compatible with each other and all use the same 11ty config with the same sensible defaults, and 11ty is built with all of the first-party plugins in mind.
You can add them all in if you still want the all-in-one-box approach, but this way lets your environments be smaller.
It’s basically pre-computed tree shaking.
There’s also a security argument for it. By splitting everything apart, you isolate security issues. If one of the random 10+ templating languages got a security issue (e.g. supply-chain attack, redos, misglobbing, etc…), it will only affect the projects that decided to use that templating language.

That’s a bad analogy.
Using an LLM for coding gives you an initial speed up with the trade off being skill atrophy, and a build up of cognitive debt in the project.
A better analogy would be the Greek government before their national debt crisis. It would have been better to invest in themselves, not lie about their own finances, and not kick the can down the road. But they kept lying and kicking the can down the road because it was easier in the short term. Of course, we all know how that turned out in the end.
