Does patching still wipe custom content?

Jidokwon

I've played through the EE versions enough now that I'd like to add a number of mods and such and start to customize the games more to my play style. In the past, though, Beamdog, in their infinite wisdom, decided to make patching wipe all custom content. Is this still the case or have they had the sense to change this?

Updates have always broken mods. I doubt there's any realistic way to change that.
