No actionables here (yet), add Blocked-on-schema-change when it actually is blocked on that.

jcrespo moved this task from Triage to Blocked external/Not db team on the DBA board.

Well, it actually is blocked on the schema change. We can't fully deploy MCR without it. But I suppose the tag is for situations where something is blocked only on the schema change.

Blocked-on-schema-change is used when the schema change is ready to go and further progress is blocked on the change actually being made on WMF's databases. In this case, we're still working out the details of what the change should be.

@Anomie is right, adding it now would only spam us and deplay actually blocked changes. Add the DBA to tell us we will be involved in the future, as a heads up, which I already did (the Blocked external is the meaning here, not the not db team, we *will* be involved, just not yet).
