I think these are all great points! I have came across Concourse CI, but have not looked too deeply into it yet.

I hadn't thought to use TOML for configuring CI pipelines, I'm curious what that might look like. TOML is indeed very flat, so it would be interesting to see what the equivalent TOML pipeline looks like compared to a YAML one.

I run Concourse CI for my personal stuff with the code in Fossil. It works decently enough, I like that it's somewhat extensible, but I have hit use cases that it can't really do like building an Alpine Linux cloud image.

As for YAML vs TOML, I am mostly sick of YAML, and I really like using TOML to configure Caddy, so I thought it might be good enough for CI config. I feel like it would be worth exploring, but maybe something slightly more complex or custom would be required.
