Yes, proxy is a type of IPC.  It's closest counterpart in the
kernel now is a named pipe.   The kernel does not try to create
named pipes automatically.  Named pipes are created deliberately
by users with the mkfifo command or system call. Same with proxy.
The proxy device nodes are application specific and need to be
created as needed by applications.

Allocation of minor numbers is an issue but that is an issue that
is separate from the proxy module itself.

Again, compare proxy to a named pipe.  It is up the application
writer to decide who gets read and write access to its proxy
nodes.
