[Investigation] ChilditemRequest - can we get rid of it?

[cielf]

Summary

Check if we can get rid of ChildItemRequest.

Details

A cursory inspection of ChildItemRequest indicated that maybe it is there to support outdated functionality from before the databases were combined.
Check thoroughly to determine whether we can, indeed, get rid of it. Are there any implications to old production data, etc.

It is possible that it is still important as a join table between the children and the requests.

This is core team because it probably requires looking at production data.

Criteria for completion

• check back with the Sunday planning meeting -- can we get rid of it?

Bonus round

• if we can, a PR to remove it.
