You could argue that for most of the zones in the DNS.  Placing more
information in a public DNS zone hardly makes a difference to general load
on the Internet (you don't have to look up a whole zone at once unless you
want to be a secondary and need to do a zone transfer, and even that isn't
strictly true with incremental transfers thesedays).  Perhaps if people
look it up a lot across the Internet, but then the funky caching features
of DNS come into play anyway.  If a zone gets too big you can always split
it up into logical subzones.  Datapoint: .com is 2GB of data.  It still
works (albeit with some gruntier hardware than normal at the backend, but
only at the backend).

Placing things in a private DNS means you have a logical disconnect with
the global DNS.  It means anyone that wants to look up stuff in the
private zone has to use one of the private zone servers.  They may also
have servers on the public Internet.  How do they know which one to query
for mlbwireless.wan or whatever?

One of the great attributes of the DNS is global consistency (similar to
IP addressing).  Don't break it without a _really_ good reason and then
only with heavy heart.  Quick hacks for short term expediency often wind
up becoming much bigger problems later on.

[Yes, I'm passionate about this!  I also realise that people are chipping
away at global consistency.  They will be sorry later.]
