Really? It's over 300 pages in length and contains plenty of vector
graphics (more text). But actually that 70 MB seems an overestimate and
I must have been looking at something else.

Here is the result of some experimentation:

23,396,929 Bytes using just \setupbackend[level=9].

21,945,243 Bytes using the aforementioned, \pdfcompresslevel9, and
\maximumpdfcompression.

23,396,827 Bytes using none of those three.

So I guess I'm still not sure which one to use since the one you said
should be sufficient doesn't seem to compress it fully.

Understood.
