I can see that leading to a lot of configuration errors and
head-scratching. Maybe YAML is not the best option after all?

Writing a parser is not hard. Why not roll your own, YAML-like?

(I personally prefer to roll my own parser. Avoids sucking in all those
bugs of existing parsing libs. And I can tailor it to my needs.)
