I'm not sure if there's other code that implements this, but if you
look at the way I do it in plone.reload [1], you'll notice that it
already does an explicit getGlobalSiteManager call and a
setSite(None). The site is set again on the next request, when
traversing over the local site object. The code also has to minimize
the ZODB cache, or the local site will have some cached info that
might have been invalidated by the global changes.

So I don't see this as a counter argument :)
