> still JSON was designed as data format

While I don't think that comments belong in JSON, I don't agree JSON is designed as "data and not code" format. Trees of tokens are actually the natural format for writing code (also known as Abstract Syntax Trees, AST) and the data/code distinction is really, really blury when those two meet together, so it's only to be expected that people will end up coding in JSON (what are the 'build definition' files for various build tools / package managers, if not very simple programs)?
