Similarly, I feel "grandfathered" implies a similar meaning as 'exempted' (which seeing elsewhere, the meaning, but not the source propagated with the word's use). Compare: The use of fax for the transmission of medics records is grandfathered. The use of fax for the transmission of medics records is exempted. Both are true, but grandfathered, as noted above, implies that it really wouldn't be allowed in today but gets to exist because some people just can't move on and look for a better technology. (In fact, many of the reasons I hate fax are features for it's die-hard users. It's fire and forget, open loop, low quality, and as easy as dialing a phone entry. Also, there's no security attached to the sender or receiver.)
