Technology is evolving and if a stop-gap is needed before the promised big splurge in 2020 (I won't hold my breath) then a hand-back or final payment as part of the deal could fit the available purse.
This thread started off with a well reasoned - "there is no money", and indeed, there wasn't. But there is now - it's just being spent on reducing the debt and revamping museums.
