Well, a non-existent copyright cannot be used to limit any access or
legal rights!
Hence, I think that it's implicitly assumed that, when no copyright
results from the compilation, the compilation itself automatically
satisfies the constraint about its copyright.

I therefore believe that non-creative compilations may more easily
(than creative ones) qualify as "aggregates".

Yes, probably.
And I could do the same with GPL-licensed photos, as long as the coffee
table book qualifies as an "aggregate".

If the coffee table book qualifies as an "aggregate", I cannot use the
compilation or its resulting copyright to limit your freedoms beyond
what is permitted by individual photos (some of which are GPL-licensed,
and thus don't permit much limiting of freedoms).

That means that you may create a derivative of the compilation, by
purging any ARR photos and keeping all the GPL-licensed ones.
You would thus obtain a coffee book table made of GPL-licensed photos
only.
You could even replace the ARR photos with other Free photos, and so
forth. After taking the ARR photos away, the coffee table book becomes
Free.
You may argue that what is left, after purging my ARR photos, is
just *your* GPL-licensed photos, in this example.
But please note that the same operation could be performed by anyone,
not just you. Moreover, maybe I created the coffee table book by
aggregating your GPL-licensed photos, not only with my ARR photos, but
also with other third-party Free photos.
I cannot restrict you from building upon my selection: you just have to
take my ARR photos away...

If the book is, say, a novel and the photos are used as pertinent
illustrations for the story, I would not call it a compilation, but a
single work.

Isn't this distinction similar to a program linked with libraries as
opposed to a collection of independent programs and libraries?

I think that the book of articles (it could be, for instance, the
proceedings of a symposium or conference) is a compilation, rather than
a single (non-compilation) work.
Hence, it may qualify as an "aggregate", as long as it satisfies the
other constraints...
