As of today, you can't change the definition, you can only deprecate
it and create a new one. On the technical side, we like to have
canonical formats, so the debate what is the canonical format would
still exist, even if we allow both formats as valid inputs.
Given that the colon format has been around for way more than 20 years
(see for example RFC 2579, STD 58), this exercise seems like a waste
of energy, it might take multiple decades to get changes widely
implemented and deployed.
