Cooling-off consternation

I am horrified by the impracticability of the cooling-off regulations [the Consumer Contract (Information, Cancellation and Additional Charges) Regulations 2013]. If, as happens, I am called out to take instructions from somebody vergens ad mortem, I can't proceed without receiving from this person (who probably can't write) a request in a durable medium. And, if I proceed without it, it would appear that I'm guilty of a criminal offence.

Apart from the barely adequate article at Journal, April 2015, 46, I have searched in vain for any comment or guidance from the Law Society of Scotland. (The (English) Law Society has issued a detailed practice note.)
I'm curious to know if our Society was consulted and, if so, what representations it made.
