> Headers which values evaluate to empty string aren't sent.

Thanks, that is the missing piece that made the problem much easier.
For some of the headers I need to conditionally set, there is no safe
default value. But since the header is not sent if the value is an
empty string, I can use proxy_set_header plus variables. That's a lot
simpler than the workaround I was going to use (building a new
headers_in structure in the subrequest).
