The problem being the typical lack of neutral - hence nowhere to put it!

That only applies to (some) retro-fits and, even then, routing in a
neutral is not impossible. Why isn't such an indicator light-switch
available for new builds where the electrician would know in advance
that a neutral is required? Is it so unusual to have the switch on the
outside of the understairs loo?

Probably not, but is not the switch being "down" enough indication
anyway?

Nope, already tried that solition and it doesn't work! see OP "We have a
loo under the stairs with the light switch on the outside and it
sometimes gets left switched on so the fan remains running (as well as
the light being on)." :=/
