I can't comment on manufacturer-supplied/supported drivers, but speaking
of my own experience with Gutenprint we can't use what we don't know
about. The tooling that could take advantage of those IDs to
provide automagic printer setup didn't exist until relatively 
recently, and by then it was a bit too late..
And much like we've seen multiple distinct models with identical USB
VID/PIDs, I've also seen distinct models that share identical IEEE1284
IDs.  And then there's the iManufacturer/iModel/iSerial strings that
may or may not match what's in the 1284 data or what's silkscreened onto
the printer itself..
...Like everything else involving printing, it's a complete mess.
(Of the stuff in Gutenprint, about a quarter of the IEEE1284 IDs, and
all of the USB VID/PIDs, were added by myself.)
 ie about a decade ago.
 They are in the same family, but the PDL is barely incompatible..
