In another other mail you said

and that function is used only in the context of ‘display-buffer’.

This would have to be done in ‘split-window’ then.  More precisely it
would have to be done in the function ‘window--sanitize-window-sizes’
which tries to make sure that all windows have reasonable sizes
according to the sizes of their margins, fringes, ...

Note one aspect though: When you shrink margins while splitting or
shrinking windows you usually won't get back their old size after
deleting the other or enlarging this window.  That's why I think that
it's much easier when packages manage their preferred size of margins in
‘window-size-change-functions’ and ‘window-configuration-change-hook’.
