Because a channel isn't always bridged when you want to swap it with
another, and there is no other operation or method to do so except for
masquerade. To get rid of masquerade would require a rearchitecture such
that bridging is always occurring, or to make everything (applications and
other APIs) aware of some kind of swap operation. These days masquerades
aren't really a huge thing like they were in the old days because it's
mostly been hidden from view and has become an internal detail. Many years
ago it would leak out into places such as AMI and be more problematic.
