What is wrong with

   texlive-collection-langczechslovak

...

Requires       : [16]                                 
    texlive-collection-basic >= 2018
    texlive-collection-latex >= 2018
    texlive-csplain >= 2018
    texlive-cslatex >= 2018
    texlive-vlna >= 2018
    texlive-cs >= 2018
    texlive-babel-czech >= 2018
    texlive-hyphen-czech >= 2018
    texlive-babel-slovak >= 2018
    texlive-cnbwp >= 2018
    texlive-csbulletin >= 2018
    texlive-cstex >= 2018
    texlive-hyphen-slovak >= 2018
    texlive-lshort-czech >= 2018
    texlive-lshort-slovak >= 2018
    texlive-texlive-cz >= 2018

If I recommend/require texlive-hyphen-czech with texlive-babel-czech then this
is also true the reverse way but as rpm does not like dependency loops this
might also cause trouble.
