Go on then, what's the ideal? Sub mains to each room with a mini-CU in
every room, with MCBs feeding individual outlets (don't laugh, it has
been suggested)? Appliance plugs with built-in MCBs rather than
replaceable cartridge fuses? Sockets with built-in MCBs, or RCBOs?
Talking of RCDs, what about changing the way we use these things?

Given that all appliances come with fitted plugs these days, it would be
easy to make the use of the wrong fuse impossible, by making the design of
the fuse and fuse carrier different for the appropriate size. And you
could also make the sale of '13 amp' extension leads not rated at 13 amps
illegal. Unless using proprietary non 13 amp connectors like some garden
tools etc, use.

The idea of having a mini CU in every room is total overkill. Just how
often does an MCB trip and cause a problem in the average house?

Since this is a DIY group, when re-wiring your house, simply put in an
adequate number of circuits. The extra costs in materials is pennies. Then
any nuisance tripping will be more localised - if it ever happens. Makes
sense to perhaps have the hall and stairs lighting on its own circuit.
