Do you perhaps mean when compress added to the existing (and already large)
postcopy test matrix?

I assume we can still add one for vanilla postcopy+compress, so it still
covers the major parts.  Or, add the compress test with the postcopy test
with most features enabled? The most comprehensive one in qtest should be:

/x86_64/migration/postcopy/preempt/recovery/tls/psk

That covers postcopy+preempt+tls, meanwhile there'll be an emulation of
network failure too during postcopy and test recovering from it.
