Michael,

Thanks for your prompt reply.

>From a client point of view deprecating and no longer requiring is quite
similar in impact - we'd need to change.

Is this discussion captured somewhere so that i could read up on it?
I'd be sad to see it go, since it has been working quite well for me (even
with raster formats) and kept the client simple.
I'd like to offer something more substantial than this knee-jerk reaction
if it still sounds like a bad idea after reading the background.

It isn't the point that clients should be separating each page into a new
document and get status back then, is it?
That would have impacts on collated copies and probably more things.
I realized only now that 2911 says multiple-document-handling "is relevant
only if a job consists of two or more documents",
but this is the only way i could see achieving collated copies on the 20+
printers i have dumps from (and it has been working well).
Furthermore, i don't see a total-collation option for jobs with multiple
documents at all...

I always saw this two-stage approach as something for advanced use-cases,
like adding cover pages and whatnot in corporate settings.
(now obsoleted by pull printing, but none the less)
In today's world i'd argue that any use-case beyond beaming over a page or
three is basically exotic.
(So while it should of course be supported, it would be nice if it wasn't
at the detriment of basic usage)

I can't help but hope future presence of this operation is based on its own
merits, not in mirroring other job types that would have a harder time
supporting it.

Br,
Anton
