electrical work for someone else to use (i.e., for sale or rental)
ought to require something like a double socket every 3 metres (in
order to reduce the need for extension leads stretched all over the
place) & to prohibit shared RCDs (in order to reduce the frequency as
well as the impact of trips).


The IET do give guidlines as to the number of sockets per room.

Good, but if they are only "guidelines", house builders will continue
to do the cheapest thing that meets the regulations....

Obviously.

It's better to wait until you decide on your layout of the house - where
things like furniture etc is going, then add sockets in the best place.

Well remember a pal who bought a new house in a small development where he
got the chance to specify more or less what he wanted. (extra cost,
obviously) And just about every socket ended up behind furniture etc so
unusable.

The user will have to trust that the designer and installer had a clue,

their cable or sockets.

But the users doesn't know the rules and may well put several high
demand loads on for days at a time, say heaters and dehumidifiers after
a flood as you appear to think no one would ever have a reason to do so.

The highest power domestic dehumidifier I've seen is 600 W (including
the built-in pump).


I actually have a ~2300W one, not really domestic though and unused for
a while now. Its really a split AC unit but it dehumidifies as well.

Ah well, in that case I can see why you need a lot of dedicated socket
circuits. :-P

Then start ripping up the floor?

Well, there is that.
