It's ok.

> For a client to create a URI, it needs data + metadata on how to create the URI.  By definition, if the client doesn't know the URI construction rules metadata, it can't construct a URI.  Hence Google, or any other site for that matter, can never construct a client side URI without the metadata/algorithm.

I believe that to be incorrect; REST requires the former, and precludes
the latter.

It is also not optimization, it is architecture; the former has superior
visibility and evolvability properties than the latter, since it's
possible for new relationships between resources to be communicated
without requiring software modifications; something that isn't possible
if the relationship is declared in some separate specification.
