Why do houses have a switch to turn the shower off, either a cord on

Can't be for safety - if you're in the shower and get a shock, if
you've
managed to get out to reach the switch, you've got away from it
anyway.

Can't be to isolate to work on it, there's a fusebox for that.

Don't need to turn it off when you're finished showering, there's a
switch on the shower itself.

If I answer this, do you promise to **** off?

It's so somebody not in the shower can isolate it quickly before
helping
the poor bugger who is being electrocuted.

I wonder why there is a requirement that the switch indicate whether it
is
on or off even when there is no power, i.e. pull switches need a 0/1
indicator (or similar), not just a neon?

So you can see if its off when it has been turned off in the CU and
you are about to turn it on again in the CU. A neon can't do that.

Under what circumstance would you need this?

If you have been working on the shower, have turned it off in the CU
to do that, and want to be next to the shower when you turn it on
again so you can burn it off again if it looks like you have ****ed up
what you have done and want to stop it destroying itself so you
can fix what you ****ed up before turning it on again.

Then remember whether you turned the isolator switch off first. Anyway the above doesn't work when the switch is in the hall.
