Are 3A plug fuses really necessary? Why not always 13A?

I think the 13a plug is the only one in the world with a fuse.
Fused plugs do exist here in the US, most often seen on Christmas tree
lights (the ones that are made here, rather than the China-built death
traps) - they have a little trapdoor in them for fuse access (US plugs
are tiny in comparison the the UK's chunk-o-rama ones :-) and a pair of
fuses that are around 10mm in length. cheers

Fusing on the neutral pole was banned here eons ago. A blown neutral
fuse causes a faulty appliance to look dead, but be live.
Yes, it ain't necessarily a good thing :-) I had a look at a couple of
strings of Chrimbo lights kicking around in the basement, and they're
both using 3A fuses.
A 10mm long fuse must have too low a breaking capacity to cope with more
current than the breaker would act on. With the US fixed wiring system's
lowish current breakers this shouldn't be a problem though.
Well ours all seem to be rated at 15A or 20A (with a few at 30A for
things such as the cooker).
