Which is when a normal signalled junction should have been installed.

Which would reduce the capacity of the junction by around 25%.

Or just have junctions with the american system of turn on red and at less
busy times simply have flashing orange on all approaches.

Turn left on red works only where it is safe to have it, and in the UK
we essentially replicate it with flow arrows and traffic islands. And
less busy times aren't the concern, it's capacity reduction and flow
balancing at *busy* times.

I do agree flashing yellow would be better than blank at part-time
lights to avoid wrong-side failures causing accidents.
