Printer device USRDRV program

I spent a bunch of time recently setting up an Okidata printer on my
iSeries, attached through an HP Jetdirect external print server.

After trying *IBMSNMPDRV and *IBMIPPDRV with no success, I opened a
Supportline call rather than beat my head against the wall.  They showed me
how to do it with a remote output queue, but I really didn't want that as
users are accustomed to 'devices' instead of 'writers' so I would get a lot
less questions if it was a device.  I could create a dummy device for the
remote output queue, but it most definitely would have caused other
problems.

After pushing Supportline that I really really really wanted a device, both
they and Roger Vicker (the same day) told me about the USRDRVPGM(TSPLPRD)
parm of the CRTDEVPRT command that was available.  TSPLPRD is a program
available in QUSRTOOL since V4.  That works great!  No problems at all so
far.  Page range and everything.

Now my question:  If this user driver program TSPLPRD has been around since
V4, why can't this be made into a true system print driver program that's
part of OS/400?  What I mean is, in addition to *IBMSNMPDRV, *IBMIPPDRV,
*IBMPJLDRV, *HPPJLDRV, and whatever other ones are out there, couldn't they
make TSPLPRD a system driver program that is used by entering *ASCIIDRV or
*IBMASCIIDRV or whatever they want to call it?

It seems simple enough to me, there must be something I don't get.  And that
wouldn't be the first time.
