I quite often have geometry in my models that is used as helping objects. Like centre lines used for mirroring. Or boundaries not be crossed. Or recently fifty clipping planes floating around.
Now, when you do Zoom Extents, locked geometry is included when it is visible. So Zoom Extents with “helpers” does not work so well. Sure you can use Zoom Selection, but it requires Select All and then zooming.
It would be handy to have a Zoom Extents that omits the locked objects.
