‘window-configuration-change-hook’ is still run way too often, for
example, when windows get resized.  ‘window-size-change-functions’ might
be better.  But if you need such a hook, wouldn't you also need it when
line numbers occupy more or less columns, for example, during scrolling?

Otherwise, why can't you use ‘display-line-numbers-mode-hook’?
