Yes, until you find that because they are totally automatic and require no tow vehicle modification, countries with cable trailer brakes use them all the time whereas countries with electric brakes have these discussions about "do I need to bother with trailer brakes?" A trailer with cable brakes fitted stops way, way better than a trailer with electric brakes that the owner hasn't bothered getting or fitting a controller for.
Anyone who tries using the cable emergency brake on their tow vehicle will find that it works just fine - but hydraulic provides better feel and less maintenance for service brakes.
I think the biggest single 'advantage' of electric brakes is how cheap they are for trailer builders to use. Cable brakes costs quite a bit more nowadays but then they don't have the cost of buying and fitting a controller - but trailer builders don't have to worry about that cost as they don't pay it.
