Why not?  Say I'm using a package that provides 50 different libraries
that wrap around various third-party image file format readers.  Each
library depends on a different third-party library for its corresponding
format.  Say my app wants to use this to read JPEG but does not care
about PNG.  Now I need to find PNG just to prevent the warning that
the package's target would need it if I linked to the png reader even
though I do not?
