Nope. It means that once /usr/bin/yum become symlink (or wrapper) to dnf, then either:
1) nothing will change because dnf is mostly compatible will yum. I would say this will be behavior for majority of 
existing scripts.
2) your script use some corner case of yum and will become broken. And you either
    a) migrate immediately to DNF
    b) you (the-sysadmin) are lazy and put it on back-burner and do s/yum/yum-legacy/ and you have to do that work from 
a) anyway one year later.
