Sorry, but I don't follow.

Why would you want the options dropped? If there have been no filters then
the options can not have been integrated into the data. So dropping them
would mean they get entirely lost. That can't be what the user wants?

And doesn't the ipp backend use FINAL_CONTENT_TYPE to determine the content
type used in the outgoing request? If it always starts sending
application/octet-stream there, then it seems rather pointless to even have
content type in the IPP protocol? We don't want to start relying on every
component having to re-detect the type, which might not even be possible
for some types of data.

And even if this somehow is sensible, how is a backend supposed to know if
CONTENT_TYPE or FINAL_CONTENT_TYPE contains the content type of the
incoming data? Looking for printer/* in FINAL_CONTENT_TYPE seems like a
crude hack, and also an unreliable one as there has historically been bugs
that caused that for other reasons.
