Technically yes, since they aren't part of the standard printing
system.  That said, there is a long history of putting drivers
(or interface scripts, or filters, etc.) in /usr/share, so it
might make sense to add a grandfather clause for this, or make
it one of several possible directories - OS vendors put them in
/usr/share, other vendors in /opt/printing/share, local drivers
in /usr/local/share, etc.

I'd say to support both - /usr for OS-supplied stuff, /opt and
/usr/local for locally-installed stuff.
