StrictYAML is great (and the author is in these comments!), but ultimately it's one specific library, not a format spec, so to depend on it for a project you need every person/tool doing the writing/parsing to commit to use that library (and the programming language it was written for).
Again, it's a great project, but I wanted something similar that is a language-agnostic format specification, so moved on to using NestedText wherever I can.
I've asked you similar in the past in comments on this site, but: what do you find lacking in the NestedText spec that a new YAML-like format might do better? Why not just embrace NestedText for the task?
