Hiding objects and clipping would seem to me unacceptable, when you consider the possibility of a button or key shortcut that would do it.
However, out of curiosity, I've always considered the option to hide an object, as an individual object hiding. But if it would hide the selection....
Oh ok, now that I'm trying it. If I select 2 objects, the Object Properties entire dialog is grayed out. So it really is made to only hide one object at a time (or lock).
I think using Layers is the current best solution. I used it extensiviely, on larger projects, and it's just become a regular part of my workflow. Although note that I'm not a professional, or really much of an artist.
