If we're setting a site, it matters that the object passed in be (or
maybe just can adapt to) an ISite; the IPossibleSite interface is for
objects that might become sites if they aren't already.

What would you expect to happen if you pass an IPossibleSite that
isn't an ISite?

I can think of at least two reasonable outcomes, and they're mutually
exclusive.  Either would surprise some portion of the user base, and I
expect that to be a substantial group in either case.

If you want to check for something at all, it should be ISite.
