I have gigabit fiber and none of this is an issue.

VLAN hopping is only possible due to misconfiguration. I'd like to be proven otherwise if that's not the case. VLANs are used EVERYWHERE where it matters. And no, the single port is absolutely not a bottleneck because the port is full-duplex.

I agree VLAN hopping is not possible without misconfiguration but it still is a "concern" for some. I also make extensive use of VLANs on my home network.

If you're trying to push close to a gigabit up and down simultaneously that single port will become a bottleneck. I agree for most typical use cases it is not a concern.

The bottleneck exists, but is a non-issue for most home use as most consumer connections are wildly asymmetric, usually biased towards download.

What happens if one node on your network is downloading at 1Gbit and another is uploading at 1Gbit?

Both get 500Mbit.

Bottleneck.

		That's going to be super rare. If it's just LAN traffic it shouldn't hit your router at all and you won't have the bottleneck issue. The actual cases would need to be quite contrived, like you're backing up your media library at the same time you're updating cod warzone.
