When the 3rd party cookies are blocked, the Visitor ID is not being
shared between different domains. I have implemented a custom code to
accomplish the Visitor.appendVisitorIDsTo(URL) solution:

you think that it would be useful to create an extension to accomplish
this in an easy way? Something like Google Tag Manager does for this
scenario that it's a simple checkbox...
If the browser rejects 3rd party cookies and you are not implementing
CNAMES(https://docs.adobe.com/help/en/id-service/using/reference/analytics-reference/cname.html)
you will need to decorate every URL that redirects the user from DomainA
to DomainB:

someday the decoration of the URL with the user ID will be able to be
automated in an easy way. Hope this helps.
