As a *user*, I look at an optdepends'ed package as an otherwise
independent package that makes the original package better or more
useful. I usually think that the original package will use the
optdepends'ed package out of the box, especially if the latter is
already installed when I install the former, or automatically if I
install the latter later. IMO, the more I have to do to configure the
main package to use the optdepends'ed package, the relationship degrades
from optdepends to something lesser.
https://wiki.archlinux.org/index.php/PKGBUILD#optdepends has some good
examples. In particular, if I see that a package has an optdepends on
CUPS, then I assume that that package detects and uses CUPS all by
itself. The package, of course, likely does lots of other things even
if it can't print.
Just my 2¢.
