Caution is commendable
I suspect that the cost of delay would be less than the potential cost of future medical lawsuits. It makes sense to pause and think before proceeding.
Having worked out what is required in order to continue, they might like to re-evaluate the projected cost and ROI. Alternatively, they might prefer to put their fingers in their ears and shout "la la la...I can't hear you". I'm sure they'll choose one of those options.
