Regarding quotes, they're optional (e.g. when you need a comma, leading whitespace, or newline). With arguments by position possible I guess colons have to be quoted too.

It's not clear to me that it's possible to convert this to a standard CSV; it can't guess the header and guessing whether a column contains units (consistent units?) is asking for trouble.

More pragmatically I can't share these with other people because they're almost like a csv, but incompatible.

It's great to try to make CSV more readable (I like the leading whitespace, but it'd be finicky to maintain with simple text editors), but not worth the technical risk of format confusion.
