- ISO 8601 is paywalled
- RFC allows a space instead of a T (e.g. 2020-12-09 16:09:…) which is nicer to read.

allows, not requires. It basically means you can use space instead of T when showing it to end users and any technical person can just use T

Development wise, It’d be better if it’s required not allowed. Best case scenario, it’s just another redundant if statement.

The amount of things allowed by ISO 8601 is even more than what’s allowed by RFC 3339, if you take the time to look at https://ijmacd.github.io/rfc3339-iso8601/
