@Martin,

I don't know why you think I'm hiding something.

I will use this when installing the rpm package using the dnf tool on the target image such as qemu or raspberrypi.

For example,

There is component A.
It needs libdrm-{nouveau,radeon,intel} packages to work properly.

When this A component rpm package is installed using dnf tool on the actual target image, 

the libdrm-{nouveau,radeon,intel} packages cannot install at once if the component A had a libdrm as rdepends.

 

However, If component A has libdrm-{nouveau,radeon,intel} as rdepends,

When these A component packages are installed using dnf, these packages can also be installed at the same time.

Because libdrm-{nouveau,radeon,intel} is not provided as RPROVIDES, these packages cannot be used as rdepends directly.
