That's totally bogus.

There are a zillion ways on most server-type platforms to do such
indirection without having to integrate it into SSH, not to mention that
almost all of those alternatives would then lead to total independence
of SSH and thus total portability across all generic transport protocols.

I.e. anything add-on client/server application (eg. file transfer) that
is simply remotely executes a server instance though an existing SSH
connection is truly independent of SSH (and any other transport

The "built-in subsystem" feature is bad design.  It has no business
being directly in the transport protocol.  It is an ugly wart.

I have no idea what that might even be.  I do not ever use any platforms
that Van Dyke Tech. current software offerings might run on (well not
without duress, and then only as dumb terminals).
