Is it really this simple?

m_idbEphemeralConnectionMap is now unused.

Yup.

There's two IDBServers - In-process and remote.
There's two IDBBackingStores - SQLite and in-memory

All we had to do was change the mix and match.

The changes in https://trac.webkit.org/changeset/242975/webkit

appears to have broken:
imported/w3c/IndexedDB-private-browsing/idbobjectstore_createIndex6-event_order.html

History:
https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=imported%2Fw3c%2FIndexedDB-private-browsing%2Fidbobjectstore_createIndex6-event_order.html

I was able to reproduce this locally using command:
run-webkit-tests imported/w3c/IndexedDB-private-browsing/idbobjectstore_createIndex6-event_order.html --iterations 500 -f

The test fails often when run on 242975 and not at all on 242974.

Looking at the dashboard, the corresponding non private browsing is also flaky with the same kind of failure.

Given we updated private IDB to be closer to regular IDB, it might be that an existing flakiness is now also happening with private IDB.
