But people frequently go out of their way to put their tabs into two dimensions.

There are tab trees: https://chromewebstore.google.com/detail/tabtree/afejdkkhibi...

There are tab groups: https://support.mozilla.org/en-US/kb/tab-groups

There are tab containers: https://addons.mozilla.org/en-US/firefox/addon/multi-account...

It seems pretty clear that people want their tabs to be organized in multiple dimensions.
