Because the only thing I need is to set the initial buffer list and
then what you described above takes care of switching tabs. This is
what we are doing:

(set-frame-parameter nil
                     'buffer-list
                     (let ((window-buffers (mapcar #'window-buffer
(window-list))))
                       (seq-filter (lambda (buffer)
                                     (or (member buffer window-buffers)
                                         (member (buffer-name buffer)
                                                 tabspaces-include-buffers)))
                                   (frame-parameter nil 'buffer-list))))
(set-frame-parameter nil
                     'buried-buffer-list
                     (seq-filter (lambda (buffer)
                                   (member (buffer-name buffer)
                                           tabspaces-include-buffers))
                                 (frame-parameter nil 'buried-buffer-list)))

tab-bar-mode takes care of the rest by doing what you describe above.
