I'm not sure if this is what you meant, but a blockchain doesn't require that every user runs a node. And any "blockchain" application usually involves some off-chain brokers for performance reasons, which yes users would have to trust to some extent, but they'd also be able to cross-check and switch brokers (or run their own) if they ever lose trust.
So a blockchain forum is doable in a similar way as NFTs. Would require caching on the read side, and unless your users are posting important enough stuff to warrant high xact fees, off-chain write batching.
The real obstacle is that like NFTs, it'd be solving a mostly theoretical problem. Barely anyone cares that a forum is owned by someone, and you need a ton of users to gain traction.
What constraints are needed? I've used DSLs that are almost Python but not quite, I think because they were hermetic and deterministic. Even those ended up being produced dynamically using some higher level config DSL or just regular code. Like once you're doing RPCs, it's general programming language territory (though there are also DSLs that do this, which is cursed).
And yes, I have very bad memories of Kubernetes YAML, also YAML itself.
I cared about programming languages when I was a newcomer. Stopped caring about 10 years ago. They're just tools, each with their own gotchas and different design choices I couldn't care less about. Between two tools that both work ok, I will definitely pick whichever one my team and I can learn the easiest, and that includes LLM coverage.
All a Mac user has needed to do was install from https://www.python.org/downloads/ and then run python3 in the shell. Even if you use MacPorts or brew or conda or whatever, there's a distinct command to run Python 3 instead of 2.
I get that Python's package manager situation is terrible, but like the other user said, you only need built-in packages to spit out a config json or whatever.
Apparently Windows XP is the dominant desktop OS in Armenia. They were savvy enough not to go to Vista I guess. (Not that the country is anywhere near large enough to skew global benchmarks.)
Which isn't really going to happen or be noticeable in this case. Yeah GC is slightly slower, but it's like blaming a 10-minute mile on your shoes. SDN or DBMS written in a GC'd language is probably not a good idea.
