I think the OCA was focused on monographs but did allow in some
serials, possibly because it wasn't clear what they were (as it can be
with bound or reprinted serials). I have warned the OL folks that
handling serials is quite complex; I think it's a good thing that they
are cutting their "bibliographic teeth" on monographs, which are
complex enough.

I don't think it's fixed in stone, but as your example below shows,
there will probably be use made of the table of contents area for
multi-volume works that have distinct titles or distinct contents.
That information will not always be available. As your example also
shows, the volume numbers may be embedded in the archive.org name for
the item, but I don't know how reliable those are. It doesn't appear
that there is a clear statement of volume number that could be
displayed, e.g. "v. 1 [link] / v. 2 [link]". If that can be derived
from the volume number in the data, then the OL folks are probably
clever enough to pull that off. My fear is that those numbers may not
have been applied consistently during the scanning process (e.g. I
believe that numbers are also used when a work is being scanned that
has already been scanned... and I do mean work, not manifestation,
although it could be either, because of how the names are derived).
