I thought there were comments specifically explaining why it was done
that way but I don't recall what they said. Perhaps it was a
performance concern since it's going to happen for every tuple put in
the tuplestore and usually you'll just be in the same memory context
anyways. It would certainly be a lot less confusing the way you
describe though.
