If the Jevko spec does not handle white space and leaves it to clients, then it will cause issues for data interchange. In order for 2 different clients to read the same Jevko file, they will need to align on how they handle white space.

For the dubious benefit of defining only three special characters (opening delimiter, closing delimiter and escaping prefix) without the usual commitment of defining a whitespace character class (like in most mainstream languages) and/or more delimiters and punctuation.

Jevko seems "simpler" than traditional syntaxes in the same way that a heap of bricks is simpler than a wall.

This is a valid concern, but on a higher-level.

Jevko leaves whitespace handling not to clients, but to formats built on Jevko which would be the thing the clients typically use (rather than plain Jevko). Such formats of course should be clearly specified, which is something I hope to get around to soon.

I already have a good candidate format for specifying first, which has 2 implementations:
