Rate Type in the Translation ledger

We are considering a change to our ledger configuration. It seems like a minor change, but it is foundational to the ledger configuration. Does anyone have experience with this setting?

PROPOSED CHANGE:
Change the ledger group “Rate Type” of the secondary ledger (ACT_USD53) from “CRRNT” to null.

Current Production Setting

With this current setting, the edit program always hits on step 1 of the hierarchy and the secondary lines always get the rate type of CRRNT regardless of what the user enters in their template. Steps 2 and 3 are irrelevant with this configuration setting.
 
Proposed Production Setting

With this proposed setting, the edit program never hits on step 1 of the hierarchy and proceeds to the second step where the edit program checks the rate type of the primary lines. If the user has specified a rate other than “CRRNT”, that same rate type is carried forward to the secondary lines.
If the user has not specified any rate type on the primary journal lines, step 3 of the hierarchy applies and the Default Rate Type of “CRRNT” applies as it does today with the current production settings.
