Well why couldn't they build a larger version of the PW ZW to compete with modern Transformers? Other manufactures still make transformers with wound coils instead of electronics. I don't think it has anything to do with safety and everything to do with cost & features. It's more economical and feature friendly to build electronically controlled transformers vs a coil wound unit.
It took Lionel a long time to get UL approval of the ZW-L, and to please UL they had to take the amperage down a bit.
There are plenty of PW ZW's out there. Why remake that, and have to compete with the secondary market?
