Why does the documentation URL for v3 Marketplace REST APIs include v4?

Why does the documentation URL for v3 Marketplace REST APIs include v4?

https://developer.atlassian.com/platform/marketplace/rest/v4/intro/

If I go to https://developer.atlassian.com/platform/marketplace/rest/v3 then I get redirected to the Product Tags REST API.

Not sure what the logic is. Does not affect my work, but it’s confusing.

You may remember them from such films as:

• UI Kit previously known as UI Kit 2, not to be confused with the original UI Kit which was renamed to UI Kit 1
• Fetch a Confluence attachment with the v2 API, not the deprecated v1 API, but if you want to create an attachment you will need to use the v1 API, that isn’t deprecated
• Products are now named apps, but not to be confused with marketplace apps, no we’re referring to Confluence and Jira as apps
