major is always the first number, calling the second a major might be a very confusing. Took me a lot of time to recover from this false belief.

It feels like a dead end here...

May I ask for a couple of more independent reviews from third parties which are not affiliated by no means with the previous reviewer and who (most importantly!) value the definition over the implementation?

The docs as is accurately describe the nuances with leading zeroes in caret ranges. Removing these sections adds more confusion because it is important to call out why this behavior exists and why one would want to use caret ranges for versions that have leading zeroes.
