OTOH, I can't imagine how you could implement a formatting function
without requiring two-pass tabs generation that is highly inefficient:
after the first pass you get the number of tabs, groups of tabs,
and their names.  Then on the second pass you can pad names
with required amount of space proportional to the total number of tabs.

So a more efficient implementation would be to modify the strings
that represent the tab names in the result of tab-bar-format-list
(e.g. by using advice-add for experimentation).  But a drawback is
that then you need to rely on the details of implementation of the
internal data structure.
