Another method: could one "surrender" a OnePulse card at a TfL office

I can't imagine the typical ticket office liking that, and you can't
always get a cash refund on Oyster cards anyway depending on how the
credit got there in the first place.

I'm intending to run mine down to zero through some careful top-ups
but I make a handful of fairly predictable journeys most weeks so it
shouldn't be too tricky to do that.
