Roll forward 3 years and I'm back at the same client working on another project. It went in better than expected and the hypercare period was reduced from 6 months to 1 month.
They said "we have 5 months extra of your time, remember that thing you said shouldn't be done, well we want you to do it"
I got their IT management to sign off full responsibility, accepting my reservations and that they as the client accepted full liability, etc.
After the project finished, they asked me why I was so reticent to do it, given how well it went in the end. I said it went well because they didn't see what had to be done - we SQL updated 170 production tables including historical ledgers that are "never touch these".
I showed them the SQLs and after they picked themselves off the floor, they asked why I was so calm about it because they finally realised how stupid/risky/dangerous it was.
