Thanks for the ideas.

The most difficult part is to choose a good option name.
Maybe, `tab-bar-history-buttons-show' is not too bad.

Sorry, I don't understand what is the problem.
When the user intentionally adds spaces in case 2.1.,
then why there is a need to trim spaces?

Do you propose to add functions that would allow doing this more easily?
Maybe using some hooks?

`winner-mode' should not be deprecated because it's still useful
for users who don't use tabs with `tab-bar-mode'.  So `winner-mode'
works fine when tabs are not used.  OTOH, `winner-mode' breaks tabs
when used with `tab-bar-mode', so `tab-bar-history-mode' is needed
to do the same when tabs are used.
