Please see for example in the branch x-tabs/lisp/tab.el.

Yes, it makes sense to have the following composite buffer-list:

 window-local buffer-list
 tab-local buffer-list
 frame-local buffer-list
 global buffer-list
 frame-local buried-buffer-list
 tab-local buried-buffer-list
 window-local buried-buffer-list

But how would you implement tab-local buffer-list without modifying
frame-local buffer-list?

A user can switch buffers inside the same tab - this modifies the
frame-local (tab-local) buffer-list.  A user can switch tabs without
using tab-bar - this updates the frame-local (tab-local) buffer-list
with the buffer-list of another tab.
