So, the concept of 'site' is part of component architecture
and not specific to application server?

Then, can we move up zope.app.component.interfaces.ISite to
zope.component.interfaces.ISite or any other place?

If we can do like this, the zope.location's dependency on
zope.app can be removed.
We are implementing 'IPhysicallyLocatable' in
zope.location.traversing.LocationPhysicallyLocatable
And there is 'getNearestSite' site method, which actually
get the 'ISite.providedBy' object.

Here is the code snip:

    def getNearestSite(self):
        """return the nearest site, see IPhysicallyLocatable"""
        if ISite.providedBy(self.context):
            return self.context
        for parent in getParents(self.context):
            if ISite.providedBy(parent):
                return parent
        return self.getRoot()
