But that is in fact the exact same thing. You're describing "why" you
want the package, not "what" you want. This is the problem that I have,
because there's an infinite number of "why"s possible.
An rpm can do something like
which seems pretty silly to me! Where does it end?

pkgfile -q KF5whatever.cmake | pacman -S -
Seems more or less "efficient" to me, but I'm not even sure why that's a
goal. package dependencies are created once, so the focus should be less
on how *fast* you can pacman -S 'the-dependency' and more on the
technical merits of conveying the information that way. And I'm
unconvinced that automatically generating "reasons" to install a package
is the right way to go here.
