Yeah I'd like to work on it. Seems like a good one to work in between bigger tasks.

I had a question about it though. I noticed that `STORE_VECTOR` is also in a similar situation. Any specific reason to leave that one as is? Or was it just an oversight? If an oversight, a second RFE could be added for that one?
