that depends on the properties of the number space used for these addresses.
DNS lacks some of the BGP features that are implicitly asked for here,
be that visibility (application of filters) or response modification based
on client identity.
The question whether the IP address space or the E.164 space will turn out
to be "more flat" in the end is moot, say: "PI".  Well, multihoming is
another interesting, albeit unrelated, issue.

So, with a BGP model being "worse" that doesn't make "DNS" a good choice,
just a less bad one. And there are other protocols that might fit even
better: using IRIS+RFC 4414 as a substrate could solve a couple of problems
at once.
