Agreed,
SpannerInTheWerks. Maybe something to talk about over a beer afterwards, but unreasonable during the Skill Test.
I also gather (anecdotally) that one CAA IRE used to give test candidates a simulated non-extinguished engine fire, then inform them on the subsequent asymmetric approach that they were still in IMC at DA/H.... Which would have been a triple emergency:
1. Engine fire and shutdown.
2. Continuing fire.
3. Weather out of limits.
