Like I said upthread, it might be reasonable to assume that the format is
fairly stable, but without a formal definition there is no way of being
certain. Formats without specifications that become popular tend to diverge,
Markdown being the textbook example.

Being a common format in ingestion tools makes it interesting though, but I
wonder if those tools aren't alreday supporting CSV such that adding logfmt
won't move the compatibility markers much?
