Indeed, but I'm trying not to categorise something as a problem before
knowing what the expected outcome was.

a slow master?) you'll be better off having the intermediary "transfer
hub" run something that can serve IXFR transfers. Bind works well for this,
even if the upstream can't do IXFRs.

Upstream can do IXFR, and the fetch process from upstream uses IXFR for 99.9% of
times (AXFR is forced every few days).
Downstream slave is the one forcing AXFR.
