[STR Resolved]

I will make this clear: you do not assign work for me. CUPS is FREE
SOFTWARE AND SUPPLIED WITHOUT ANY WARRANTY.

PPD deprecation was widely discussed five years ago.  It has been covered
extensively in the OpenPrinting summits for the last five years.  It even
made the pages of Slashdot.  All of the documentation says that PPDs are
deprecated.  If you compile software that uses the PPD APIs you get a
deprecation warning unless you disable them (or your Linux distribution
patches the warning away).  In short, PPDs are dead, and support for them
will be removed as soon as it is feasible to do so.

Likewise, the driver interface deprecation was communicated in an
OpenPrinting summit and is documented in the man page for cups-driverd. 
The performance problem is simple: driver interfaces took too long to run
and used huge amounts of resources (several minutes to load, several
gigabytes of memory in one case) and some implementations tried to talk to
local printers (explicitly disallowed in the original definition of the
interface).  There was no way to make the interface work well, so we killed
it.
