Why not to unify git mr and git pr into one command?

I have in my script git-req (much more primitive than yours) this:

repo_url="$(git config --get remote.origin.url)"
if [[ "${repo_url}" =~ gitlab ]] ; then
    rem_ref_name="merge-requests"
    loc_ref_name="mr"
else
    rem_ref_name="pull"
    loc_ref_name="pr"
fi
