Yes, that is the way to go, also for non-Mac-OS-X systems we want to get 
rid of the 1980's hack. Therefore we are already working on this at 
OpenPrinting. Printer Applications (this is how these local IPP servers 
are called) will not only be able to replace classic printer drivers but 
also SANE scanner drivers (there is also an IPP driverless scanning 
standard) and even configuring the Printer Application and the Printer 
and also maintaining/cleaning/firmware-updating the printer (for all 
this there is IPP System Service). So a Printer Application can support 
a multi-function device with all its bells and whistles.

For the quick convert of classic drivers into Printer Applications 
(printing only) there was a GSoC project this year:

I had also a mini conference on Linux Plumber's this year about this:

In the next GSoC scanning implementations are planned. Making a Printer 
Application of GutenPrint was also one of my ideas for a GSoC project in 
2020.
