What things?Useless single-functionality ports take up space. Space that could be used for other things.
How much will it impact you to carry a small USB-C hub for all these ports you so desperatly need? It won't change anything on the current MacBook. This should have ZERO impact on you.
I carry a hub, but if it's built in, what's the problem?
Again, what other "things" can they put there besides ports??
Also carry a hub, is in fact an impact, you need to carry it with you.
