if nothing changed between v11 and v12, can we not simply do pub type V11HostConfiguration = V12HostConfiguration
?

Yes, that is what I've done initially but decided to make it a different struct to avoid any missuses as we have many unreleased migrations and another one not merged here: #3181
Superseded by: polkadot-fellows/runtimes#205 |
This one enables feature bit 1 (Elastic scaling MVP) but doesn't alter the structure.
Once the migration is done, upgraded nodes can include
CoreIndex
in backed candidates that are passed to the parachains inherent. Runtime already supports this injectedCoreIndex
. See #3231 and #3229
