I did :-) There are excellent reasons why variable length IPv6 addresses would have been a bad idea. That is why I separated considerations for IP layer, DNS and Applications.
At the application layer, the concerns are very different. Variable length identifiers are not a problem. We use them in RFC822, ASN.1, XML and JSON.
I do not see we MUST have variable length addresses in whatever protocol we have.
In DNS for example, we do not. Yes, lots of them, but not unlimited number of them.
