[tantek]There's also the yearless date, e.g. many birthdays or holidays/anniversaries are entered with just the month and the day, which in ISO8601 is something like --03-17
[tantek]I'd lean towards keeping Z bc it's such a common use case and likely worth the brevity vs slightly more consuming code trade-off, though I’m sympathetic to that too
sknebelvcp supports less formats, yes. but the change should not break any of the otherwise possible formats (e.g. whats in HTML spec as datetime values)
sknebelI think the framing should be something like "if temporary value matches the following pattern, normalize it as follows: <> if this other pattern, as follows: <> otherwise, pass through unchanged"
