Only one prefix, zh-Latn. The prefix is a recommendation for best practice, and overall users will have much better results with zh-Latn-wadegile than zh-wadegile. While *we* may know that wadegile is inherently Latn, software implementations won't know that unless they are told, and the likelihood of that happening, particularly in existing implementations, is virtually nil.

Type: variant
Subtag: wadegile
Description: Wade-Giles romanization of Chinese
Prefix: zh-Latn

Both? As I have said wadegile is inherently Latn, not Grek or Cyrl or
