I feel the same way. Keep limited tabs open most of the time.

But the advantage to vertical and nested tabs is that when I need to open a dozen links (like grabbing interesting links from a page without stopping mid flow) I can do it without having to ruin my environment. The tabs are there ready to be consumed: nicely nested below the source tab. Doing that with a horizontal tab bar would destroy my productivity until I closed all of those tabs. It allows you to switch tasks.

As far as wasted space… I hardly ever use a laptop screen. Text content is ideal at 70ch? That’s like a 1/3rd of a 27” monitor.
