it means everything. It means that actually you are not obligated to have a swordman style to be at the top of your might - raylegh with 1 or 2 Sword and doesn't Caring about it or shanks losing an arm and still becoming stronger than mihawk by reaching yonko tier says it all.
You are not worthy to be a top tier among top tier if you don't have it.
And thus Oda invented Wss title to help them Cope. and mf was prime example : mihawk did nothing nor was he considered as incredible despite beeing muh Wss.
Oh and it Also means you don't have to Cope with a mere différence in color in your Sword.
Found this while googling for Ryuma fanart , this gentleman says that you can't be Top top tier without CoC, i suppose that Zoro is already beyond the top tier amongst top tiers level because he not only has conquerors but he can use it at a level that wasn't previously known to be possible and he's still weaker than Mihawk.
How does one cope after saying nonsense like this and the manga goes and make Mihawk's student one of the very strongest because of CoC?
