Yes, we have this issue as well. I can understand why it would be slightly complicated for them to implement on the back-end but I would suggest it goes something like this:
1) Duplicate items are found in Inventory
2) Check items you wish to merge and complete merge
3) All recurring invoices using the old SKUs will now point to the new merged SKU
4) Leave old transactions alone and simply apply this to new transactions
