Since part of the job of a Captain is to develop and teach the FOs, why not take it and use it as a learning point (with the caveats listed above)?
After landing look at the fuel and debrief. If he/she has more than the tonne remaining then congratulate them on managing their energy well and discuss whether if it was necessary to take the extra gas. If less, why was that? what could be done differently? Or was it a good decision to carry extra.
Depending on the sector and the tankering gain/loss, you may find the lessons identified may exceed the cost of the fuel and self-confidence. Just food for thought.
p.s. It’s not just trainers that can develop FOs
