I donìt get this argument.
Aside for the fact that "only six companions" would be disappointing regardless of party size, if anything reducing the number of slots is going to make me even more wary of experimenting with the occasional odd class/specialization. When you have only four slots, each one of them becomes even more valuable to cover for a key role, rather than trying fancy combinations and synergies.
