I've made a couple of small additions to the Upstream Tracking section
Specifically, Honza Horak pointed out Petr Hracek's Rebase Helper 
and the ROSA Labs API/ABI analysis tools  as being relevant to the
"Upstream Release Monitoring" piece.
That doesn't change the overall shape of the proposed pipeline, but it
does highlight that there's more to the "Upstream Release Monitoring"
piece than just tracking and reporting those releases in Anitya.
