It's not a bad option but it does mean you can't have text where every line is indented. This isn't uncommon - e.g. think about code generation of a function body.
Right, this is a pretty common syntax, but doesn't address the same problem as Zig's syntax.
I've only seen two that do: the Zig approach, and a postprocessing ‘dedent’ step.
Why couldn't you have it?
You just put the ending """ where you want it relative to the content.
