My point of view thereabout is that a user should know, when seeing a
"printer-driver-*" package that "if I want my ${FOO} printer to work, I should
find one amongst those to make it work". So the printer-driver-* packages
should provide "what makes it work", either directly or trough dependencies.

Hmm; not really. As far as I understand it, e.g. c2050 is a printer driver
package, and it only provides two binaries: c2050 and ps2lexmark.

Again, I'm not sure that's a good-enough measure.

Hmm. What is the difference between hpijs and hpijs-ppds ? Wouldn't it be
possible to pyppd-compress the PPDs of the latter and merge them back
(again?). This is confusing (to me…).

Sounds sane, but I confess that most of the hpijs <-> hplip picture is still
blurry to me.
