I agree Gary the 'system' is far from perfect.
But the risks of non-disclosure are pretty significant as the OP implies above. Other than obvious signs such as changes in cable colour, different make accessories, date of manufactured accessories, visible disturbance to the building the worst one of all is that people talk and that is the problem and maybe out of revenge.
Are the ramifications worth it? In the extreme a distress warrant could be issued upon the new owner and that new owner having to have the entire place rewired. And will that new owner just sit back and pay for these costs plus other losses? I think not in these days of suing at the slightest whim the original seller could find himself out of pocket by quite a lot along with possibly being prosecuted.
You have the options and you take your choice.
