No, "the goal of domain names is to provide a mechanism for naming resources in such a way that the names are usable in different hosts, networks, protocol families, internets, and administrative organizations" and they "are not required to have a one-to-one correspondence with host names, host addresses, or any other type of information."
DNS is 15 years older then HTTP so of course it's not meant to be used that way. Domain names where put in different configuration files once, and then your mail client, IRC client, NTP client and so on just worked forever. With HTTP you suddenly started to use domain names by typing them over and over agian.
Personally I'm not sure the web will look like this in the future. I think domain names will be hidden from users once again. Netflix will of course use domain names internally to get content from their servers, but the user only needs to find the Netflix app from som App-store.
I don't see how email addresses were much different than HTTP URLs - they just worked iļ¬ you had a contact stored, but that's equivalent to bookmarks.
I also don't see domain names becoming invisible any time soon, simply because linking is too damn useful, and most companies have to incentive to destroy that.
