+1 to inline tables being extremely hard to use, even for experienced devs.

I wouldn't expect the inherit clause to lead to merged lists, because "inherit" sounds so all-or-nothing. "+" is more intuitive that way. Maybe this is just a naming thing though – if you don't intend to use it for primitives, "merge_with_parent" or something like that could work.

What about separate extend vs inherit directives?

“Extend” would do the job!
