I don't think it makes a difference, serf will generate the error in
both cases.

Serf is decompressing the HTTP body of the REPORT. At the Subversion
level the body is an XML <S:update-report> but as far as serf is
concerned it is just a block of data that has to be decompressed. Serf
doesn't look to see whether the uncompressed data really is XML so it
certainly doesn't care whether there is one <S:txdelta> or many.
